Question

If I roll a dice 120 times how many times I expect to get a 2

Answer 1

If one rolls a dice 120 times, he/she expect to get a 2, 20 time

Explanation:

The probability of getting a 2 when the dice is rolled 1 time is
`(1)/(6)`

Given - The dice is rolled for 120 times

Probability of getting a 2 is

`(1)/(6) *120\\= 20`

Thus, if one rolls a dice 120 times, he/she expect to get a 2, 20 time
