Answer:

5 times a 6 can be expected in 30 times.

Step-by-step explanation:

A die is rolled 30 times.

We have to find how many time a 6 can be expected in 30 times.

Probability of getting 6 in 1 time = [tex]\frac{1}{6}[/tex]

⇒ Probability of getting 6 in 30 time = [tex]\frac{1}{6}\times30[/tex]

                                                             = 5 times

Therefore, 5 times a 6 can be expected in 30 times.
