UGC-NET | UGC NET CS 2015 Jun – II | Question 2

Consider an experiment of tossing two fair dice, one black and one red. What is the probability that the number on the black die divides the number on red die?
(A) 22 / 36
(B) 12 / 36
(C) 14 / 36
(D) 6 / 36


Answer: (C)

Explanation: We have two dice one is black other one is red:
There will be total 36 outcome.
We have to find the probability of outcome of first dice divides outcome of second one.
1 divides 1, 2, 3, 4, 5, 6.
2 divides 2, 4, 6.
3 divides 3, 6.
4 divides 4.
5 divides 5.
6 divides 6.
There are 14 number which will be counted in favourable outcome;
probability = favorable outcome / total outcome.
i.e. = 14 / 36.
So, option (C) is correct.
