Question

If two number cubes are rolled what is the probability of rolling two numbers with a sum less than or equal to 10

Answer 1

`p = (11)/(12)`

Explanation:

If we roll two number cubes we can summarize the results in the following table (Check table in the attachment)

According to table of sum we roll two numbers with a sum less than or equal to 10 in 33 cases out of a total of 36 result

Then

The probability of rolling two numbers with a sum less than or equal to 10 is: 33/36 = 11/12
