A bag contains 5 quarters, 2 dimes, and 4 pennies. What is the probability of picking a quarter?

• 5/11

Find the theoretical probability of NOT landing on yellow if you spin the spinner.

• 1/8

• 7/8

• 1

• 7

Which of the following describes theoretical probability?

•   Perform an experiment to determine the probability

•       Determining the expected probability of an event

• Perform a simulation and count the number of possible outcomes

• Use trials to count the number of desired outcomes

Vy is shopping for a car. It comes in red, blue, or silver. She can also choose a 2-door and 4-door version along with a manual or automatic transmission. What is the theoretical probability that Vy will pick 4-door car, automatic transmission and it being red or blue?

Experimental Probability is:

• What Will happen 

• What actually happens

• What should happen

• What I think Happens

• A

• B

• C

• D

as the number of trials in an experiment increases, the experimental probability of an event approaches the theoretical probability of the same event, meaning the difference between the experimental and theoretical probability will be closer to zero 

• fundamental counting principal 

• independent event

• inference

• law of large numbers

Ricardo has the spinner pictured here and a bag of marbles filled with 2 red marbles, 3 green marbles, and 3 blue marbles. What is the probability that Ricardo spins red on the spinner and picks a red marble out of the bag?

• 1 ⁄ 16

• 1 ⁄ 2

• 1 ⁄ 4

• 1 ⁄ 8

Shannon has a bag of jelly beans. She removed one jelly bean, recording the color, and then replaced it. She repeated the process 44 times and record her results in the table. What is the experimental probability of her selecting a red jelly bean?
