Question

Two fair 6 sided number cubes are rolled. What is the probability of rolling a sum of 11?

Question 3 options:

1/6

1/36

1/18

11/36

Answer 1

Draw a sample space diagram showing the sum of rolling two dice. It should be 6 rows by 6 columns therefore there are 36 different outcomes possible.
There are two ways to make a sum of 11: 5,6 or 6,5. This means that the probability is 2/36 which equals 1/18.
