Question

A die is rolled twice. Find the probability that 5 will come up both the times.

Short Note
Sum

Solution

Total number of outcomes = 36.

Cases where 5 comes up on exactly two times is (5, 5).

Number of such cases = 1.

∴ P(5 will come up both the times) = `("Number of favourable outcomes")/"Number of all possible outcomes"` 

`= 1/36`

Thus, the probability that 5 will come up both the times is `1/36`.
