**Find the probability and odds of simple events.**

2
The probability of an event—the ratio of the number of favorable outcomes for the event to the total number of possible outcomes. EXAMPLE: When you flip a coin, there are two possible outcomes. The probability of getting a heads is 1:2 or

3
**Sample space—list of all possible outcomes.**

When you roll a die, there are six possible outcomes: 1, 2, 3, 4, 5, or 6. What is the sample space of spinning this spinner?

4
When there are n outcomes and the probability of each one is 1 𝑛 , we say that the outcomes are equally likely. For example, when you roll a die, the 6 possible outcomes are equally likely because each outcome has a probability of The probability of an event is always between 0 and 1, inclusive. The closer a probability is to 1, the more likely it is to occur.

A bowl contains 5 red chips, 7 blue chips, 6 yellow chips, and 10 green chips. One chip is randomly drawn. Find each probability. a. blue 1 4 11 28 b. red or yellow 9 14 c. not green

7
One method used for counting the number of possible outcomes is to draw a tree diagram. The last column of a tree diagram shows all of the possible outcomes.
