During a fund-raising drive, 500 raffle tickets are old at $1 each. One ticket will win the  first prize worth $20; 3 tickets will win second-prizes worth $10 each; and 10 tickets will  win third-prizes worth $5 each. Assuming that each person buys only one ticket, let x be a  ticket buyer’s net winnings. (a) Find the probability distribution of x. (b) Find the probability that a ticket buyer wins no more than $10. (c) Find the mean of x. Interpret the answer in plain language.
