Question

Three dice are thrown simultaneously. Calculate the probability of getting triplet of odd number.
1. 1/45
2. 1/72
3. 5/72
4. 1/216

Answer 1

Correct Answer - Option 2 : 1/72

Formula used:

Probability = Total number of outcomes/ Sample space

Calculation:

Sample space = 6 × 6 × 6

⇒ Sample space = 216

Number of possible outcomes = {(1, 1, 1), (3, 3, 3), (5, 5, 5)}

⇒ Number of possible outcomes = 3

Required probability = 3/ 216

∴ required probability is 1/ 72
