Multiple Choice

Assuming that the spinner is fair, choose the statement below that is true:

• The larger the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability.

• The experimental probability will never be very close to the theoretical probability, no matter the number of spins.

• The smaller the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability.

Multiple Choice

What is the main difference between theoretical probability and experimental probability?

• Theoretical probability is based on expected outcomes using math, while experimental probability is based on actual results from experiments.

• Theoretical probability is always more accurate than experimental probability.

• Experimental probability is used only for coin flips.

• Theoretical probability does not require any calculations.
