The one-time fling! 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 5% 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? (Round your answers to three decimal places.)<\/span><\/p>\n

(a) no one has done a one-time fling________<\/span><\/p>\n

\u00a0<\/span><\/p>\n

(b) at least one person has done a one-time fling_______<\/span><\/p>\n

\u00a0<\/span><\/p>\n

(c) no more than two people have done a one-time fling_________<\/span><\/p>\n

A research team conducted a study showing that approximately 25% of all businessmen who wear ties wear them so tightly that they actually reduce blood flow to the brain, diminishing cerebral functions. At a board meeting of 15 businessmen, all of whom wear ties, what are the following probabilities? (Round your answers to three decimal places.)<\/span><\/p>\n

(a) at least one tie is too tight________<\/span><\/p>\n
