Creating a Number Line for Probability D 25% 50% 75% 100% 0% On a piece of paper, you are to make a number line and then place these events color-coded on the number line based on the probability of each event. (1)You will get heads on the toss of a coin. (2) You can run 20 miles in one hour. (3) You will roll a number 6 on a number cube. (4) It will snow in Minnesota this winter. (5) The sun will rise tomorrow. (6) You will toss a coin twice and get tails both times. (7) You will toss a coin twice and get heads at least once. (8) You will attend school tomorrow.

Experimental Probability Making Purple At a carnival, there is a game of chance called making purple. It requires during a player’s turn to spin a spinner two times. To make purple, a player must land on red or blue first and then red/blue on the second spin. Each turn of two spins cost $1 with a winner to receive a $10 prize. We will perform an experiment and record the results.

Making Purple Making a prediction Do you think the carnival game will make a profit for the owner of Making Purple? Explain your reasoning.

Making Purple Make a two column chart in your notebook to record the results: Yes No http://www.mathplayground.com/probability.html

Making Purple Use the results to answer the following questions: (1) How many times was the game played? How many times was the game won? (2) Did the carnival owner make a profit? Explain how you figured this out. (3) What is the theoretical probability(use a percent) of any player winning Making Purple on one turn? (4) How would the theoretical probability change if a player could land only on red, then blue on a turn? Answers will vary based on experimental results of each class for #1 and #2. #3 would be 4%. #4 would be 4%
