Question

I have two fair dice each numbered 1 to 6 I throw both dice and add the two numbers together. What is the probability that the number I get is a multiple of 5 .

Answer 1

7 / 36

Explanation:

Using the sample space attached,

Required outcome = multiple of 5 from the sun of two rolled dice = 7

Total possible outcomes =(number of faces)² = 6² = 36

Therefore, the probability of obtaining a sum which is a multiple of 5 is :

P(sum which is a multiple of 5) :

Required outcome / Total possible outcomes

= 7 / 36
