Chapter 10 Review

Use the spinner to determine the theoretical probability of the event.

Spinning a 7

• $\frac{1}{8}$

• $\frac{7}{8}$

• $\frac{1}{7}$

• $\frac{1}{15}$

Use the spinner to determine the theoretical probability of the event.

Spinning a number less than 3

• $\frac{1}{4}$

• $\frac{3}{8}$

• $\frac{2}{8}$

• $\frac{1}{8}$

Use the spinner to determine the theoretical probability of the event.

Spinning a number greater than 10

• 0

• 1

• $\frac{1}{10}$

You check 50 pencils. 32 of them are not sharpened. What is the probability that the pencil you check is not sharpened?

You check 50 pencils. 32 of them are not sharpened. Out of the next 75 pencils you check, how many would you expect to not be sharpened? _____ pencils

**On the test, you will need to write a proportion to solve.

You have a jar with the following marbles: 4 blue, 8 red, 2 green

You randomly choose one marble from the jar. Find the theoretical probability of choosing one red marble.

• $\frac{4}{7}$

• $\frac{8}{14}$

• $\frac{4}{3}$

• $\frac{8}{11}$

You have two sticks. Each stick has one pink side and one blue side. You throw the sticks 15 times and record the results. Use the table to find the experimental probability of the event.

Tossing 2 blue

• $\frac{4}{15}$

• $\frac{1}{3}$

• $\frac{1}{2}$

• $\frac{4}{11}$

You have two sticks. Each stick has one pink side and one blue side. You throw the sticks 15 times and record the results. Use the table to find the experimental probability of the event.

Tossing 1 blue and 1 pink

• $\frac{8}{15}$

• $\frac{8}{7}$

• $\frac{8}{11}$

• $\frac{1}{2}$

Use the bar graph to find the experimental probability of drawing a yellow or orange marble.
