Explanation:
Detailed explanation-1: -If by a “standard number cube” you mean an unbiased six-sided die with the sides numbered 1-6, the probability of rolling one of them is 2/6 or 1/3.
Detailed explanation-2: -The probability of rolling an odd number on a fair 6-sided number cube is 1/2.
Detailed explanation-3: -Out of the 6 possibilities, we don’t want 1 of them. That means that the other 5 are all fair game. Therefore, the probability of not rolling a 3 on a regular die is 5/6, or about 83%. A number cube is rolled 120 times.
