head or a six?

= 1/2*5/6=5/12

Answer 2

Grrrr. I forgot the 1
Pr (head or six)=1=5/12=7/12

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

Answer 4

1/4
