1: Chance Experiments How likely it is that some events will occur? Suppose you and your friend will play a game using the spinner shown here: Dr. Basta Grade 7, Module 5, Lesson 11 Player 1Player 2

How fair is this game? Who do you think will win the game? Will it make a difference who goes first? Do you think this game is fair? Dr. Basta Grade 7, Module 5, Lesson 12

What are the chances green will win? Dr. Basta Grade 7, Module 5, Lesson 13 Spinner B, because the green section is larger for this spinner than for the other spinners. Which spinner gives green the best chances to win?

What is Probability? Dr. Basta Grade 7, Module 5, Lesson 14

What are my chances? Dr. Basta Grade 7, Module 5, Lesson 15 You have a bag with two green cubes, and you select one at random. What is the chance of selecting a blue cube? There is no way to select a blue cube if there are no blue cubes in the bag. FractionDecimalPercentage 0.00%

What are my chances? Dr. Basta Grade 7, Module 5, Lesson 16 You have a bag with two green cubes, and you select one at random. What are the chances of selecting a green cube? You will always get a green cube if there are only green cubes in the bag. FractionDecimalPercentage %

What are my chances? Dr. Basta Grade 7, Module 5, Lesson 17 You have a bag with one blue cube and one red cube and you randomly pick one. What are the chances of selecting a blue cube? You will select a blue cube one-half of the time. FractionDecimalPercentage 0.550%

What are my chances? Dr. Basta Grade 7, Module 5, Lesson 18 FractionDecimalPercentage If you have a bag that contains eight blue cubes and two red cubes, and you select one at random, it is unlikely that you will get a red cube. Even though it is not impossible to get a red cube, a red cube would not be selected very often because there are many more blue cubes than red cubes.

What are my chances? Dr. Basta Grade 7, Module 5, Lesson 19 FractionDecimalPercentage 0.5 < P(B) < 150% < P(B) < 100% If you have a bag that contains eight blue cubes and two red cubes, and you select one at random, it is likely that you will get a blue cube. Even though it is not certain that you will get a blue cube, a blue cube would be selected most of the time because there are many more blue cubes than red cubes.
