Have you ever purchased an article of clothing (dress, sports jacket, etc.), worn the item once to a party, and then returned the purchase? This is called a one-time fling. About 10% of all adults deliberately do a one-time fling and feel no guilt about it! (Source: Are You Normal? by Bernice Kanner, St. Martin's Press.) In a group of seven adult friends, what is the probability that:

a) no one has done a one-time fling?

b) at least one person has done a one-time fling?
