A die is rolled twice. What is the probability of getting a sum equal ...
Total number of outcomes possible when a die is rolled = 6 (∵ any one face out of the 6 faces)
- Hence, total number of outcomes possible when a die is rolled twice, n(S) = 6 x 6 = 36
E = Getting a sum of 9 when the two dice fall = {(3,6), (4,5), (5,4), (6,3)}
- Hence, n(E) = 4

A die is rolled twice. What is the probability of getting a sum equal ...
Total pair 6*6 = 36
and pair whose sum is = 9 i.e= (6,3), (3,6) ,(5,4) and (4,5)
so probability of getting sum equal to 9 = 4/36= 1/9
and pair whose sum is = 9 i.e= (6,3), (3,6) ,(5,4) and (4,5)
so probability of getting sum equal to 9 = 4/36= 1/9
