Explanation:
Detailed explanation-1: -Summary: A regular number cube is rolled. The probability that a 3 will not be rolled is 5/6.
Detailed explanation-2: -Let’s say P = probability of getting a 6 on each throw = 1/6. P’ = probability of NOT getting a 6 on each throw is 1-p = 5/6.
Detailed explanation-3: -Explanation: There are only 6 sides on a die, and only 1 of them is 6, so there is a 16 chance of rolling a 6.
Detailed explanation-4: -Simply subtract 125 from 216 which will give us the chances a 6 WILL appear when three dice are rolled, which is 91. 91 out of 216 or 42.1 %.
