Q31 of 66 Page 15

Two difference dice are rolled simultaneously. Find the probability that the sum of the numbers on the two dice is 10.[CBSE 2014]

Total numbers of elementary events are: 6 x6 = 36

Let E be the event of getting the sum of the numbers on the two dice is 10


The favourable combination is: (5, 5), (4, 6), (6, 4)


The numbers of favourable combinations are: 3


∴ P (getting sum of numbers on the dice is 10) = P (E) = 3/36 = 1/12
