Question

Three dice are thrown simultaneously. What is the probability of getting a sum of 18?
1. 1/216
2. 1/9
3. 1/6
4. 1/36

Answer 1

Correct Answer - Option 1 : 1/216

Given: 

Total outcomes when three dice rolled simultaneously. 6³ = 216

Formula Used:

Probability = (possible outcomes/Total outcomes)

Calculation: 

Total outcomes when three dice rolled simultaneously,

⇒ 63 = 216

Possible outcome to getting of sum of 18,

⇒ (6, 6, 6) = 1 

Probability = 1/216

∴ The probability of getting a sum of 18 is 1/216
