Question

Jessica rolled two six-sided number cubes with sides numbered 1 through 6. The list below shows the possible outcomes when rolling the two number cubes. 1, 1 1, 2 1, 3 1, 4 1, 5 1, 6 2, 1 2, 2 2, 3 2, 4 2, 5 2, 6 3, 1 3, 2 3, 3 3, 4 3, 5 3, 6 4, 1 4, 2 4, 3 4, 4 4, 5 4, 6 5, 1 5, 2 5, 3 5, 4 5, 5 5, 6 6, 1 6, 2 6, 3 6, 4 6, 5 6, 6 What is the probability of the sum of the numbers on the number cubes equaling 9? HELPPPPP

Answer 1

The list of possible outcomes in the question is totally incomprehensible.  But from our vast experience with questions like this and dice in general, we know there are 36 of them.

Now, here are all the ways to roll a total of 9:

3, 6
6, 3
4, 5
5, 4

Four of the 36 possible rolls result in a 9.
So the probability (with honest dice) is 4/36 = 1/9 = 11.1% .
