About 15% of all adults deliberately do a one-time fling and feel no guilt about it! In a group of eight adult friends, what is the probability of the following? a. no one has done a one time fling
b. at least one person has done a one time fling
c. no more than two people have done a one time fling

Step-by-step explanation:

--- 8 friends

--- proportion that one-time fling

Rewrite as:

Solving (c): --- Not more than 2 has one time fling

This is calculated as:

We have:
