The one-time fling! have you ever purchased an article of clothing (dress, sports jacket, worn the item once to a party, and then returned the purchase? this is called a one-time fling. about 20% of all adults deliberately do a one-time fling and feel no guilt about it! in a group of nine adult friends, what is the probability of the following?

Given that about 20% of adults do one time fling.

That is probability of a person doing fling is . Let it be p.

Then we have to use binomial distribution formula for the given problems.

b(x;n,p)=

A)Probability of no one has done one time fling means x is 0 here.

Hence

b) Probability of at least one person has done fling=1-(probability of no one has done)

                                                                                    =1-0.1342=0.8658

c)Probability of no more than two people have done one time fling means we need to add the probabilities for x=1,x=2 along with x=0.

Hence probability = 0.1342+0.302+0.302 = 0.7382

4 + 5 7/9= 9 7/9
