Suppose you pay $10 to play a card game with the following rules:
You draw 2 cards out of a standard deck of 52 cards without replacement.
If the 2 cards are of the same suit (i.e. both clubs, both diamonds, etc) you win $15 (a $5 profit).
If the 2 cards are the same value (i.e. both jacks, both 2's, etc) you win $18 (an $8 profit).
a) If you play this game what is your expected winnings or loss (to the nearest cent)?
b) Is winning money at this game an unusual event? (hint: consider making an interval of ordinary values around the mean).
