Home » Aptitude » Probability » Question

Two dice are thrown simultaneously. What is the probability of getting a number other than 4 on any dice ?

1. 25/36
2. 1/3
3. 17/36
4. 2/3

Correct Option: A

Here, n(S) = 6 x 6 = 36 and E = Event of getting a number other than 4 on any dice
= {(1, 1), (1, 2), (1, 3), (1, 5), (1, 6), (2, 1), (2, 2) , (2, 3) , (2, 5), (2, 6), (3, 1), (3, 2), (3, 3), (3, 5), (3, 6), (5, 1) , (5, 2) , (5, 3), (5, 5), (5, 6), (6, 1), (6, 2), (6, 3), (6, 5), (6, 6) }
∴ P(E) = n(E) / n(S) = 25/36
