Lue is rolling a random number cube. The cube has six sides, and each one is labeled with a different number one through six. What is the probability he will roll a or a on one roll? .

Each number has an equal probability of being rolled. Since there are total sides, what is the probability of getting any number?

Each number has a one-in-six probability of being rolled. Since we can roll either a or a , we can add the probabilities of these two numbers together.

Use the eTool to find the probability of rolling a or a .
