Question

A six-sided die is rolled. What is the probability of NOT rolling a 1 or 6?

Answer 1

`(2)/(3)`

Explanation:

"The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible".

Here the number of favorable outcomes is 4, and the number of total outcomes is 6.

So the probability of NOT rolling a 1 or 6 is
`(4)/(6)` which is
`(2)/(3)`
