Question

When two dice are thrown, the probability of getting a number always greater than 4 on the second dice is ....

(A) 1/6

(B) 1/3

(C) 1/36

(D) 5/36

Answer 1

The correct option is: (B) 1/3

Explanation:

Total number of outcomes when two dice are thrown = 36

Let A be the event of getting a number always greater than 4 on second dice.

. ^.. A = {(1, 5), (1, 6), (2,5), (2,6), (3, 5), (3, 6), (4, 5), (4, 6), (5, s), (5, 6), (6, s), (6, 6)) 

.'. Number of possible outcomes = 12

. ^.. P(A) = 12/36 = 1/3
