I have the same problem as found in this link https://www.coursehero.com/tutors-problems/Statistics-and-Probability/10284983-The-Centers-for-Disease-Control-and-Prevention-CDC-is-required-by-la/?justUnlocked=1

I don't believe the answer given answered the final question listed below:

SuspiciousSamples?

"Write an explanation that answers the question, 'Is it possible to select at random 10 ART cycles that did not result in a clinical pregnancy?' Include in your explanation the appropriate probability distribution and your calculation of the probability of no clinical pregnancies in 10 ART cycles."

(a) Selecting at random 10 ART cycles among women of age 40, eight of which resulted in clinical pregnancies.

(b) Selecting at random 10 ART cycles among women of age 41, none of which resulted in clinical pregnancies.

But if they did answer these questions can you explain it to me? Thanks.
