Theoretical Probability vs Experimental Probability and Predictions

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

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?

Theoretical Probability is?

• What Should happen

• What does happen

• What Will Happen

• What I want to Happen

P(not A) = 
*Remember to simplify.*

• 6/8

• 3/4

• 2/8

• 1/4

Determine the type of probability:

Damon flipped a coin 50 times and got 31 heads.

Based on the results, the probability of heads is 31/50, or 62%.

• Theoretical Probability

• Experimental Probability

Theoretically, what is the probability that you will land on a 3?

• 25%

• 50%

• 75%

• 0%

Kate spun the spinner 75 times and landed on "3" thirty times.

What is the experimental probability as a percentage?

• 20%

• 30%

• 40%

• 50%

Sarah hit the ball 3 times out of the 8 times.

What is the experimental probability (as a percent) that she will hit the ball next?

• 22.5%

• 37.5%

• 45%

• 3%
