Question

If you rolled a number cube 72 times, how many times would you expect a value less than a 5?

Answer 1

48

Explanation:

Since there are 6 sides to a fair regular die, we'd expect each number to be rolled `1/6` of the time.

`1/6xx72=12` times.

We'd expect 12 ones, 12 twos, 12 threes and 12 fours = 48 rolls (the other 24 rolls would be fives and sixes).
