You are rolling two dice at the same time. What is the probability of rolling a sum of 5 or 9?
First, we can take a look at all of the
Possibility of 5
We can check the table to see which results sum to
We could do this even without the table because of an understanding of the numbers that sum to
Possibility of 9
We can apply the same principles as before to this problem.
Checking the table, we see that the following sum to
There are other combination that sum to
Therefore, we again have
