Lucy rolls 2 fair dice and adds the results from each. Work out the probability of getting a total that is a multiple of 5.

Multiples of 5  =  5  and 10

Ways to roll a 5  =  (1,4) ( 4,1)  (2,3) (3,2)

Ways to roll  a 10   =  (5,5) (4,6) (6,4)

We have  7  possible outcomes for a multiple of 5...and there are   36  possible outcomes in total 

So  P (multiple of 5)    = 7 / 36
