Find the probability of rolling divisors of 30. note: these questions are based on rolling one die.

The correct answer is:

5/6.

Explanation:

The numbers on the sides of a die are:

1, 2, 3, 4, 5, 6

Out of these, the following are factors of 30:

1, 2, 3, 5, 6

This makes 5 numbers out of 6 total, for a probability of 5/6.

Justin did not eat 7/12 of the pizza

Step-by-step explanation:

Marc eats 1/6 × 24 = 4, 24 - 4 = 20 left over

Claudine eats 1/4 × 20= 5, 20 - 5 = 15 left over

Sylvia eats 1/3 × 15 = 5, 15 - 5 = 10 left over

Justin eats 10.

24 - 10 = 14

Justin did not eat 14/24 = 7/12
