Lesson 8.1 - Up to Chance

Match the following probabilities with the scenario

• What is the most likely probability to open to a page between 1 to 100 in a history textbook?

• What is the most likely probability to open to a page between 1 to 10 in a short children's book?

• What is the most likely probability to open to a page between 21 to 31 in a long chapter book?

• What is the most likely probability to open to page 103 in a dictionary?

What is the probability of the spinner landing on the section labeled G?

On an assignment, there are two true or false questions. You guess on both questions.

What is the probability that you get ONE question right by guessing?

The spinner is spun 1,000 times. What is the best estimate for the number of times it would be expected to lang on the section labeled B?

• 16

• 60

You are creating a spinner with each sector evenly distributed as 25% of the circle.

What is the measure of the central angle formed from three of the sectors?

The circle in the image has been divided into congruent sectors.

What is the measure of the central angle of the shaded region?

• 4.7 degrees

• 12 degrees

• 15 degrees

• 30 degrees

Select ALL the following games that would be considered a chance experiment.

• Game 1: A watermelon eating contest. The fastest to eat a wedge of watermelon WINS!

• Game 2: Two cubes have a face labeled "WIN!". If both cubes land on "WIN!" facing up, then you WIN!

• Game 3: A ball is placed under 1 of 5 cups. The cups are shuffled around. The player chooses a cup. If the ball is underneath that cup, they WIN!

• Game 4: Players push a button that starts lighting up different regions of the board. The game is rigged because every 5th person will WIN!
