CCSS Content Standards Mathematical Practices 1 Make sense of problems and persevere in solving them. 2 Reason abstractly and quantitatively.

Then/Now You calculated experimental probability. Use lists, tables, and tree diagrams to represent sample spaces. Use the Fundamental Counting Principle to count outcomes.

Vocabulary sample space tree diagram two-stage experiment multi-stage experiment Fundamental Counting Principle

Example 1 Represent a Sample Space One red token and one black token are placed in a bag. A token is drawn and the color is recorded. It is then returned to the bag and a second draw is made. Represent the sample space for this experiment by making an organized list a table, and a tree diagram. Organized List Pair each possible outcome from the first drawing with the possible outcomes from the second drawing. R, RB, B R, BB, R

Example 1 Represent a Sample Space Table List the outcomes of the first drawing in the left column and those of the second drawing in the top row.

Example 1 Represent a Sample Space Tree Diagram

Example 1 One yellow token and one blue token are placed in a bag. A token is drawn and the color is recorded. It is then returned to the bag and a second draw is made. Choose the correct display of this sample space. A.B. C.D.Y, Y; B, B; Y, B

Example 1 One yellow token and one blue token are placed in a bag. A token is drawn and the color is recorded. It is then returned to the bag and a second draw is made. Choose the correct display of this sample space. A.B. C.D.Y, Y; B, B; Y, B

Example 2 Multi-Stage Tree Diagrams CHEF’S SALAD A chef’s salad at a local restaurant comes with a choice of French, ranch, or blue cheese dressings and optional toppings of cheese, turkey, and eggs. Draw a tree diagram to represent the sample space for salad orders. The sample space is the result of 4 stages. ●Dressing (F, R, or BC) ●Cheese (C or NC) ●Turkey (T or NT) ●Eggs (E or NE) Draw a tree diagram with 4 stages.
