Numbers is a game where you bet $1 on any three-digit number from 000 to 999. If your number comes up, you get $600.00, otherwise you lose the $1. Find your expected winnings if all numbers are equally likely to come up.

  there are 1000 numbers from 000 to 999 so the prob of any one coming up is 1/1000 the expected winning = 1/1000(600) = .60 or 60¢. (not smart to play that game)
