Finding Experimental and Theoretical Probability

What is the theoretical probability of the spinner landing on yellow?

• 1/4

• 1/2

• 1/3

• 2/3

The spinner was spun 30 times and landed on blue 12 times. What was the experimental probability of the spinner landing on colors that were not blue?

• 2/5

• 3/5

• 4/5

• 1/5

What is the theoretical probability for rolling a number greater than 4?

• 1/6

• 1/3

• 1/2

• 2/3

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

What is the probability of flipping a coin and getting heads?

• 1/2

• 1/3

• 1/4

• Never, Tails never fails.

What is the probability that you will get plain crust with ham on your pizza?

• 1/8

• 1/₂

• 1/₁₀

• 2/₁₀

If the spinner above is spun and the coin is flipped, create a tree diagram to represent the probability of getting a blue AND a heads. Which answer represents the probability?

• 1/6

• 4/12

• 1/4

• 1/8

Probability is defined as...

• the set of all possible outcomes.

• the likelihood that an event will happen.

• the fundamental counting principle.
