Binomial distribution. surveys repeatedly show that about 40% of adults in the u. s. indicate that if they only had one child, they would prefer it to be a boy. suppose we took a random sample of 15 adults and the number who indicated they preferred a boy was 8. this would be considered a rare event because the probability of 8 or more is so low.

true/false

False

Step-by-step explanation:

We are given the following information:

We treat adult who prefer one child to be a boy as a success.

P(prefer one child to be a boy) = 40% = 0.4

Then the number of adults follows a binomial distribution, where

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 15 and x = 8

We have to evaluate:

Since the probability of 8 or more is 0.2131 is not very small, thus, it is not a rare event.

Thus, the given statement is false.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
