A company has a 20-person grievance committee. When a grievance is filed, three of these 20 people are chosen at random to serve on a hearing panel. Suppose that two committees are formed. What is the probability that these committees have at least one member in common?
Answers
Answer:
the probability that the two committees have at least one member in common is approximately 0.3622.
Step-by-step explanation:
To find the probability that two committees have at least one member in common, we can use the complement rule, which states that the probability of an event happening is 1 minus the probability of the event not happening.
Let A be the event that the two committees have no members in common. To calculate the probability of A, we can first find the number of ways to choose three people out of 20 without any overlap, and then use this to find the total number of ways to choose two committees of three people each without any overlap:
Number of ways to choose 3 people out of 20 without overlap:
C(20,3) = (201918)/(321) = 1140
Number of ways to choose 3 people out of 20 with overlap:
C(20,3) - C(2,1)C(17,2) = 1140 - 2(2*136) = 680
The first term is the total number of ways to choose 3 people out of 20, and the second term is the number of ways to choose 3 people out of 20 such that one particular person is included. We multiply by 2 because there are two committees.
The total number of ways to choose two committees of three people each without any overlap is:
C(20,3) * C(17,3) = (1140*680) = 775200
Therefore, the probability that the two committees have no members in common is:
P(A) = 775200 / (C(20,3)*C(17,3)) = 0.6378
So the probability that the two committees have at least one member in common is:
P(at least one member in common) = 1 - P(A) = 1 - 0.6378 = 0.3622
Therefore, the probability that the two committees have at least one member in common is approximately 0.3622.

Carla asked students at a lunch table what their main course they liked. Out of these students, 28n liked pizza, 15 liked chicken nuggets, and 8 liked both. what is the probability that a randomly selected student will like pizza but not chicken nuggets?
Answers
The probability that a randomly selected student will like pizza but not chicken nuggets is (28n - 8)/(28n + 7), where 28n is the students who like pizza and 8 is students who like both pizza and chicken nuggets.
To find the probability that a randomly selected student will like pizza but not chicken nuggets.
Let P = the number of students who like pizza but not chicken nuggets
Then, P = the number of students who like pizza - the number of students who like both pizza and chicken nuggets
P = 28n - 8
So, the probability that a randomly selected student will like pizza but not chicken nuggets is:
P(Pizza but not nuggets) = P/(Total number of students)
We can find the total number of students who like either pizza or chicken nuggets by adding the number of students who like pizza and the number of students who like chicken nuggets, and then subtracting the number of students who like both:
Total number of students = 28n + 15 - 8 = 28n + 7
So, the probability that a randomly selected student will like pizza but not chicken nuggets is:
P(Pizza but not nuggets) = P/(Total number of students) = (28n - 8)/(28n + 7)

Answers
Answer:
(C) Multiply first equation by -2 and second equation by 3, solution (1, 1)
Step-by-step explanation:
Simultaneous equations:Simultaneous equations are set of equations which possess a common solution. The equations can be solved by eliminating one of the unknowns by multiplying each of the equations in a way that a common coefficient is obtained in the unknown to be eliminated.
Given the simultaneous equations:
3x - 5y = -2
2x + y = 3
First step:
Multiply first equation by -2 and multiply second equation by 3,
-6x + 10y = 4
6x + 3y = 9
Second step:
Add the two equations together,
13y = 13
Divide both sides by 13
y = 1
Third step:
Put y = 1 in the first equation
3x - 5(1) = -2
3x - 5 = -2
3x = 5 - 2
3x = 3
Divide both sides by 3:
x = 1

A teacher wishes to choose a group of students to help with a presentation. If he needs 2 boys and 3
girls to help with the project and has 14 boys and 12 girls in his classroom, in how many ways can he
make the selection?
Answers
Choosing 2 boys can be done in 14 x 13 = 182 ways.
But this puts them in order ( first and second) which is not required so the unordered number ways is 182 / 2 = 91
Choosing 3 girls can be done in 12 x 11 x 10 = 1320 ways but 3 girls can appear in 3! ways = 6.
The number of unordered selections of 3 girls = 1320 / 6 = 220
The total number of selections is 91 x 220 = 20020.
If you thought the answer was 240240 it is because you used permutations rather than combinations.

A passenger train leaves depot 2 hours after a freight train leaves the same depot. The freight train is traveling 18 mph slower than the freight train find the rate of each train if the passenger train over, takes the freight train in 3 hours
Answers
Answer:
The passenger train is traveling at 45 mph, and the freight train is traveling at 27 mph.
Step-by-step explanation:
Let's assume the speed of the passenger train is represented by x mph.
According to the given information, the freight train leaves the depot 2 hours before the passenger train. Therefore, when the passenger train starts, the freight train has already been traveling for 2 hours.
Let's represent the speed of the freight train as (x - 18) mph, which is 18 mph slower than the passenger train.
Now, we know that the passenger train overtakes the freight train in 3 hours. This means that the passenger train traveled for 3 hours, while the freight train traveled for 3 + 2 = 5 hours.
Since speed = distance/time, we can set up the following equation based on the distances covered by each train:
Distance covered by passenger train = Distance covered by freight train
Using the formula, distance = speed × time, we get:
x × 3 = (x - 18) × 5
Simplifying the equation:
3x = 5x - 90
90 = 5x - 3x
90 = 2x
Dividing both sides by 2:
45 = x
So, the speed of the passenger train is 45 mph.
The speed of the freight train is 45 - 18 = 27 mph.
Assume the heights in a female population are normally distributed with mean 65.7 inches and standard deviation 3.2 inches. Then the probability that a typical female from this population is between 5 feet and 5 feet 7 inches tall is (to the nearest three decimals) which of the following?
a. 0.620
b. 0.658
c. 0.963
Answers
Answer:
Choice a. approximately \(0.62\).
Step-by-step explanation:
This explanation shows how to solve this problem using a typical \(z\)-score table. Consider a normal distribution with mean \(\mu\) and variance \(\sigma^2\). The \(z\!\)-score for a measurement of value \(x\) would be \((x - \mu) / \sigma\).
Convert all heights to inches:
\(5\; \rm ft = 5 \times 12 \; in = 60\; \rm in\).\(5\; \rm ft + 7\; \rm in = 5 \times 12 \; in + 7\; \rm in = 67\; \rm in\).Let \(X\) represent the height (in inches) of a female from this population. By the assumptions in this question: \(X \sim \mathrm{N}(65.7,\, 3.2)\). The question is asking for the probability \(P(60 \le X \le 67)\). Calculate the \(z\) score for the two boundary values:
For the lower bound, \(60\; \rm in\): \(\displaystyle z = \frac{60 - 65.7}{3.2} \approx -1.78\).For the upper bound, \(67\; \rm in\): \(\displaystyle z = \frac{67 - 65.7}{3.2} \approx 0.41\).Look up the corresponding probabilities on a typical \(z\)-score table.
For the \(z\)-score of the upper bound, the corresponding probability is approximately \(0.6591\). In other words:
\(P(x \le 67) \approx 0.6591\)
On the other hand, some \(z\)-score table might not include the probability for negative \(z\!\) scores. That missing part can be found using the symmetry of the normal distribution PDF.
The probability corresponding to \(P(z < 1.78)\) (that's the opposite of the \(z\!\)-score at the lower bound) is approximately \(0.9625\). By the symmetry of the normal PDF:
\(P(z < -1.78) = 1 - P(z < 0 - (-1.78)) \approx 1 - 0.9625 = 0.0375\).
Therefore:
\(P(X < 60) \approx 0.0375\).
Calculate the probability of the interval between the two bounds:
\(\begin{aligned}P(60 \le X \le 65.7) &= P(X \le 65.7) - P(X \le 60)\\ &\approx 0.6591 - 0.0375 \approx 0.62 \end{aligned}\).

Answers
Answer:
B. More
Step-by-step explanation:
This is according to the law of large numbers
An experimental probability is more likely to approach the theoretical probability if the number of trials simulated is larger.
What is an experimental probability and theoretical probability?Experimental probability is an experimental outcome whereas theoretical probability is a possible or expected outcome.
An experimental probability is more likely to approach the theoretical probability if the number of trials increased because of the law of large numbers which states that the average of the results obtained from a large number of trials should be close to the expected value and tends to become closer to the expected value as more trials are performed
Thus using the concept of the law of large numbers we can say that an experimental probability is more likely to approach the theoretical probability.

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
Answers
Answer:
x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your
x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).

Answers
Answer:
We know that:
Over a half-mile stretch of road, there are 7 evenly spaced street signs.
If we assume that there is a sign right at the beginning and another right at the end, then the distance between each sign will be equal to the total distance divided by the total number of signs minus one because the distance is measured in pairs of consecutive signs, if we have 7 signs, then we will have 6 pairs of consecutive ones ( 1st and 2nd, 2nd and 3rd, 3rd and 4th, ...)
(0.5mi)/6 = 0.83... mi
So, rounding to the second decimal after the decimal point, the distance between each sign is 0.83 miles.
