Question

Jenny has a 6-sided number cube. If Jenny rolls the number cube 180 times, how many times can Jenny predict she

will roll a 1?

Answer 1

30 times

Explanation:

Firstly, we need the probability of rolling a 1

That will be 1/6

So for 180 rolls, the equivalent number of times will be;

1/6 * 180 = 30
