Question

A fair die is rolled 20 times, and the desirable outcomes are 2, 3, 5 or 6. Calculate the probability that the desirable even occurs five times?

Answer 1

Answer #1

Out of 6 outcomes, 2 outcomes 2 and 6 are desirable even outcomes so the probability of getting desirable even outcome in single roll is

3 3

So the probability that the desirable even occurs five times is

20 (1 220-5

Answer 2
