  1. Making Predictions Based On Theoretical Probability We are learning to…find theoretical probability and then make a prediction based on the probability. Wednesday, April 2, 2014

  2. Yellow Blue Red Green Blue What is the theoretical probability of spinning a yellow? ¼ ¼ ½ ½ ¼ ¼ The probability of spinning a yellow is ¼…because ¼ of the spinner is yellow. If you would spin the spinner 100 times how many times would you expect to get yellow? Number of times spinning yellow Probability of spinning yellow is… So… Total number of times spinning If you spin the spinner 100 times you would expect to have the result of yellow 25 times.

  3. Yellow Blue Red Green Blue What is the theoretical probability of spinning a red ¼ ¼ ½ ½ 1/8 ¼ The probability of spinning a red is 1/8…because 1/8 of the spinner is red. ¼ 1/8 If you would spin the spinner 1000 times how many times would you expect to get red? Number of times spinning red Probability of spinning red is… So… Total number of times spinning If you spin the spinner 1000 times you would expect to have the result of red 125 times.

  4. Yellow Blue Red Green Blue What is the theoretical probability of spinning a blue 1/8 ¼ ¼ 1/8 1/8 ¼ 1/8 The probability of spinning a blue is 3/8…because 3/8 of the spinner is blue. If you would spin the spinner 800 times how many times would you expect to get blue? Number of times spinning blue Probability of spinning blue is… So… Total number of times spinning If you spin the spinner 800 times you would expect to have the result of blue 300 times.

  5. 5 2 8 11 Group Practice • In an experiment Yolanda is rolling a number cube and spinning a spinner with the number 2, 5, 8, and 11. She then finds the sum of the two results. Step 1: With your group create a Tree Diagram or Area Model that could be used to find all the possible outcomes of this experiment. Step 2: Then with your group find the Theoretical Probability of several different events and predict the number of outcomes for that event. Step 3: Finally show your teacher your solutions to move on to your homework assignment.
