Question

Two dice are rolled once. Find the probability of getting such numbers on the two dice, whose product is 12.
OR
A box contains 80 discs which are numbered from 1 to 80. If one disc is drawn at random from box, find the probability that it bears a perfect square number.

Answer 1

1/12 is the right answer because only in three situations we get the product of number 12
i.e.(2,6),(3,4),(4,3).
