Question

A fair die is rolled three times. A 4 considered success while all other outcomes are failures. Find the probability of each number of successes.

Answer 1

Probability of success = 1/6.

Explanation:

A die has 6 sides, all different assuming the die is fair. If a 4 is the ONLY successful outcome, the probability of a successful outcome is 1/6, and the probability of a failed outcome is 5/6, because 5 of the 6 sides are not the number 4.
