Question

A pair of dice is thrown. What is the probability of getting an even number on the first die or a total of 8?

Answer 1

n(s) = 36

A = {(2,6), (6,2), (3,5), (5,3), (4,4) 
(2,1), (2,2), (2,3), (2,4), (2,5) 
(4,1), (4,2), (4,3), (4,5), (4,6) 
(6,1), (6,3), (6,4), (6,5), (6,6)}

P(A)=`("n"("A"))/("n"("S"))=20/36=10/18=5/9`
