Question

In throwing three dices probability to get same digit on all three is –

(A) 1/36

(B) 3/22

(C) 1/6

(D) 1/18

Answer 1

Answer is (A) 1/36

∵ A = {(1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5), (6, 6, 6)}

n(A) = 6, n(S) = 6³ = 216

Required probability

= n(A)/n(S) = 6/216

= 1/36
