Suppose that someone offers you a bet concerning the tossing of a pair of fair dice. If both die turn up the same number, you will win $24. Otherwise you must pay $6 . Your expected winnings would be ________.
A.
$1.00
B.
$6.00
C.
-$1.00
D.
-$6.00
P(double) = 6/36 = 1/6
so E = 1/6 * 24 - 5/6 * 6 = 6-5 = 1
