Question

A single die is rolled on time. Find the probability of rollung a number greater than 5 or less than 4​

Answer 1

`(2)/(3)`

Explanation:

A single die is rolled on time.

All possible outcomes are
`1,2,3,4,5,6` (6 in total)

Rolling a number greater than 5 or less than 4​ means rolling numbers
`6` or
`1,2,3` so

All favorable outcomes are
`1,2,3,6` (4 in total)

The probability of rolling a number greater than 5 or less than 4​ is

`P=\frac{\text{Number of all favorable outcomes }}{\text{Number of all possible outcomes}}\\ \\=(4)/(6)\\ \\=(2)/(3)`
