Question

Four standard six-sided dice are to be rolled. What is the probability that the product of the numbers on the top faces will be prime?

Answer 1

Answer: The probability is 1/2

Step-by-step explanation:

A die has 6 sides, 3 of which are prime numbers. These are 2, 3 and 5.

There are 4 dice so there are 24 faces.

Only 3 numbers on the dice are prime.

So 3 prime numbers on 4 dice would be 12 numbers.

12 prime numbers/24 total numbers

=1/2
