Randall is playing a game that involves drawing a card from a deck. There are 10 cards numbered from 1 to 10. If Randall draws a card with a multiple of 3, he wins 5 points. If he draws any other card, he loses 3 points. What is Randall's expected point score when he draws a card?

    -3

    3, 6 and 9 are multiples of 3. This means he has a 3/10 chance of getting +5 and 7/10 chance of a -3.

    I hope this helps a little more. Thanks for asking.
