I have never found a forum where people are nice enough to help you out as people do on here... it's greatly appreciated... with that said one more question, lol:
The Book Sweepstakes mails 20,000,000 entry forms of which
Winnings 3 10 500 5000 10000 25000 100000
Number 12000 7900 90 4 3 2 1
If you enter this sweepstakes, what is the probability that you will win something? Is your expected return more than the cost of mailing a first class letter?
