Q23 of 98 Page 686

Two dice are rolled together. Find the probability of getting such numbers on the two dice whose product is 12.

Total numbers of elementary events are: 6x6 = 36

Let E be the elementary event of getting numbers on the two dice whose product is 12


The favourable outcomes are: (2, 6), (3, 4), (4, 3), (6, 2)


Then, the numbers of favourable outcomes = 4


∴ P (numbers on the two dice whose product is 12) = P (E) = 4/36 = 1/9
