Question

You roll a 6-sided die.

What is P(factor of 90)?
Write your answer as a fraction or whole number.

Answer 1

P(factor of 90) = 5/6

Explanation:

When you roll a 6 sided die, it can land showing a 1, 2, 3, 4, 5 or 6. All these numbers except for 4 are factors of 90.

That is 1 goes into 90.

2 goes into 90.

3 goes into 90.

4 does not go into 90.

5 goes into 90.

6 goes into 90.

So 5 out of the 6 sides show a number that goes into 90.

5 of 6 numbers are factors of 90.

So, P(factorof90)

= 5/6
