Pre-Ap Probability and Statistics

Emma is playing a spinning game using the spinner shown. She gets one spin and needs green to win. What's probability that she will NOT win?

• .25

• .75

• .70

• 40

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?

• a.  Perform an experiment to determine the probability

• a.      Determining the expected probability of an event

• a.  Perform a simulation and count the number of possible outcomes

• a.  Use trials to count the number of desired outcomes

Experimental Probability is:

• What Will happen 

• What actually happens

• What should happen

• What I think Happens

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

• 5/11

• 5/6

• 1/3

• 5

How many people watched more than 6 hours of TV?

• 10

• 5

• 20

• 17

How many employees have a salary less than $22,000?

• 50

• 350

• 0

• 10

How many people went to the amusement park fewer than 3 times?

• 1

• 2

• 10

• 8

• 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
