Compare Probabilities

Which event is more likely, rolling a six sided number cube and getting an even number, or tossing a coin and having it land heads up?

• even number on the number cube

• heads up with a coin toss

• equally likely

• I don't know - I don't have any dice or money

A number that tells how likely an event is to happen.

• probability

• outcome

• event

• simulation

Of all 25 marbles in a bag, 3 of the marbles are white. What is the probability that a white marble will be randomly selected from the bag without looking? Write your answer as a percent. ________%

A bag contains 80 colored tokens. Of all the tokens in the bag, 25 are black and the rest are red. Find, in percent form, the probability of choosing a black token from this bag. The probability of choosing a black token is ________%.

• A

• B

• C

• D

An event with probability 3/4 is more likely to happen than an event with probability 4/5?​

True or False (put T or F)

The theoretical probability is ​ ​ ​ (a)  

The experimental probability is ​ ​ (b)  

The experimental probability is ​ (c)   the theoretical probability.

• 120/200

• 3/5

• equal to

• 37%

• much smaller than

• much larger than

• close to

• 120%

• 37/200

• the same as

On the image, place a point for the event that has the greater likelihood of happening:

Flipping two coins and getting at least one head --OR-- rolling an even number on a die

A 6-sided fair die is rolled 12 times. The results are listed below.

2, 4, 5, 4, 3, 6, 4, 3, 1, 5, 2, 4

Compare the theoretical and experimental probability of getting a 2.

• The theoretical probability is greater than the experimental

• The theoretical probability is less than the experimental

• The theoretical and experimental probabilities are the same

• Cannot be determined
