Question

A fair dice is rolled. Work out the probability of getting a factor of 12.

Answer 1

5/6

Explanation:

well, 1,2,3,4 and 6 are factors of 12.

and a fair sided dice has 6 sides.

so 5 out of those 6 sides are factors of 12.

The only on that is not is 5

Answer 2

P (factors of 12) = 5/6

Explanation:

The possibilities are 1,2,3,4,5,6

Factors of 12 are 1,2,3,4,6,12

So out of the possibilities rolled

1,2,3,4,6 are factors of 12 (5 of the 6)

P (factors of 12) = 5/6
