If a die is rolled 4 times, what is the probability that 6 comes up at least once?

Solution:

It is given that

A die is rolled 4 times

We have to find the probability that 6 comes up atleast once

We know that

On 1 roll P (not 6) = ⅚

So for 4 rolls, P (no 6) = (⅚)4 = 0.482253

Here the P(at least one 6) = 1 - P (no 6)

Substituting the values

= 1 - 0.482253

= 0.517747

= 52%

Therefore, the probability that 6 comes up at least once is 52%.

If a die is rolled 4 times, what is the probability that 6 comes up at least once?

Summary:

If a die is rolled 4 times, the probability that 6 comes up at least once is 52%.
