Question

Three dice are thrown. What is the probability that at least one of the numbers turning up being greater than 4?​

Answer 1

Answer:

Since outcomes having no 4′s and outcomes having at least one (4) are mutually exclusive, we can use the complement rule of probability: Outcomes containing at least one occurrence of 4 when rolling 3 dice: Therefore, 91 of the 216 possible 3 dice roll outcomes contain at least one (4).
