3. In a particular game, a fair die is tossed. If the number of spots showing is either four or five, you win \$1. If the number of spots showing is six, you win \$4. And if the number of spots showing is one, two, or three, you win nothing. You are going to play game twice.

The probability that you win \$4 both times is

a)1/6
b)1/3
c)1/36
d)1/4
e)1/12
