  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
