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 ten possibilities for each number, so the probability of getting any one number is .1 or 1/10.

The probability of all events occurring (getting all three winning numbers) is found by multiplying the probability of the individual events.

Can you do that?
