Question

Malachy rolls a fair dice 720 times.
How many times would Malachy expect to roll a five?​

Answer 1

120 times

Explanation:

On a dice, there are 6 sides.

Since one of these sides is a 5, the chance of rolling a five is 1/6.

Find how many times Malachy can expect to roll a five by multiplying 720 by 1/6:

720(1/6)

= 120

So, Malachy can expect to roll a five 120 times
