Question

Dan rolls 2 fair dice and adds the results from each.

Work out the probability of getting a total that is a factor of 15.

Answer 1

Explanation:

1. there are six squares in each dice so 3×5=15 and 5×3=15
2. answer is 1/8

Answer 2

`(1)/(18)`

Explanation:

If there are six sides on a die then there are 36 different rolls

The factors of 15 are (3×5) and (5×3) so you would get 2/36

When you simplify that you get 1/18

I hope this helps!!
