Answer 2

Answer:

If two dice are thrown ,

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

n(s) = 36

Probability of getting 9

S = { (3,6) (4,5) (5,4) (6,3) }

n(S) = 4
