Answer:
Step-by-step explanation:
Recall the definition for conditional probability.
We have P(A/D) = P(A and D)/P(D)
P(AD) = 2/17
P(A) = 8/17 and P(D) = 10/17
From the definition of conditional probability,
P(A/D) = P(AD)/P(D) = 2/17 divided by 10/17 = 1/5
But P(D/A) = P(AD)/P(A) = 2/17 divided by 8/17 = 1/4
Hence the two are not equal.
This is because there is a difference in the denominators
One standard deviation below the mean is 36.7
One standard deviation above to mean is 53.3
Idk which one your looking for
Answer:
It is not possible
Step-by-step explanation:
First 6 people have 9 friends and since 6 people can have totally the same friends which could all be each other, we would have 5 friends(from same 6 people) + 4 friends(not from the 6). Therefore we would have total 9 people/students
In second group of 8 people, their friends could entirely be the same be the same as the first group's friends or they could all be each other's friend hence just an additional 8 students to the population
In the third group of 11 people/students, same thing could apply as above but total number of students would always surpass 25 with the additional population. Example 9+8+11= 28
Therefore it is not possible that 25 students would each have those number of friends.
