Probability Practice

What is the theoretical probability that an even number will be rolled on a number cube?

• 1/3

• 1/2

• 2/3

• 1/6

What is the difference between theoretical and experimental probability?

• Experimental Probability is what should happen while Theoretical Probability is what does happen.

• Theoretical Probability is what should happen while Experimental Probability is what does happen.

• There is no difference.

• One is a fraction and one is a decimal.

Experimental Probability is:

• What Will happen 
• What actually happens
• What should happen
• What I think Happens

  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

What is the probability of spinning a blue or red?

• unlikely

• equally likely

• likely

• certain

What type of probability is used to find the probability of an event when all outcomes are equally as likely. "What COULD happen"

• Experimental Probability

• Theoretical Probability

What type of probability is a way of estimating the probability of an event happening based on repeated trials?

• Experimental Probabillity

• Theoretical Probability

Jon made 15 out of 35 free throws.

What is his experimental probability as a fraction?

**SIMPLIFY THE FRACTION!**

• 3/7

• 15/35

• 1/2

• 5/7

The probability of flipping a coin and landing on tails is 1/2.
If you flip the coin 100 times, approximately how many times could you expect to land on tails?

• 50 times
• 100 times
• 200 times

A bag has 4 green marbles, 3 red, 2 blue and 1 yellow. What is the theoretical probability of pulling a red?

• 3/10

• 3/6

• 1/9

• 1/3
