### Example Question #2 : Data Analysis

If a standard die is rolled, what is the probability of getting a 1 or a 2?     Explanation:

We need to know the total number of possibilities, and the total number of ways to achieve our goal.

A standard die has 6 faces, so there are a total of 6 numbers that we could roll.

We want to roll a 1 or a 2, which means there are 2 ways that we can succeed (rolling a 1 or a 2).

Thus, we have a probability of success as which reduces to .

### Example Question #1 : How To Find The Answer From A Table Ten friends go out for drinks. They order four sodas, two coffees, two iced teas, a milk, and a hot tea.
