An Experiment consists of flipping a fair coin once and rolling a fair die once. what is the probability of observing a hear or six?

head or a six?
Pr(head or six)= 1Pr(tail and not a six)
= 1/2*5/6=5/12 
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 
1/4
