7.16 A box contains five slips of paper, marked $1, $1,
$1, $10, and $25. The winner of a contest selects two slips of paper at random and then gets the larger of the dollar amounts on the two slips. Define a random variable w by w = amount awarded. Determine the probability distribu- tion of w. (Hint: Think of the slips as numbered 1, 2, 3, 4, and 5, so that an outcome of the experiment consists of two of these numbers.)
7.14 Of all airline flight requests received by a certain discount ticket broker, 70% are for domestic travel (D) and 30% are for international flights (I). Let x be the num- ber of requests among the next three requests received that are for domestic flights. Assuming independence of suc- cessive requests, determine the probability distribution of
x. (Hint: One possible outcome is DID, with the probabil- ity (.7)(.3)(.7) = .147.)1
