Mary Jane spins the spinner 15 times. The arrow lands 6 times on a star and 9 times on the heart. Which THREE statements are correct when comparing the experimental and theoretical probabilities?

Question

Mary Jane spins the spinner 15 times. The arrow lands 6 times on a star and 9 times on the heart. Which THREE statements are correct when comparing the experimental and theoretical probabilities?

Responses

A The theoretical probability for landing on the star is greater than the experimental probability.The theoretical probability for landing on the star is greater than the experimental probability.

B The experimental probability for landing on the heart is greater than the theoretical probability.The experimental probability for landing on the heart is greater than the theoretical probability.

C The experimental probability for landing on the star is greater than the theoretical probability.The experimental probability for landing on the star is greater than the theoretical probability.

D As the number of spins increases, the closer the experimental probability will get to the theoretical probability.As the number of spins increases, the closer the experimental probability will get to the theoretical probability.

E The experimental probability for landing on the heart is less than the theoretical probability.The experimental probability for landing on the heart is less than the theoretical probability.

Answer 1

B, C, and D are the correct statements. The experimental probability for landing on the heart (9/15 or 0.6) is greater than the theoretical probability (0.5). The experimental probability for landing on the star (6/15 or 0.4) is also greater than the theoretical probability (0.5). As the number of spins increases, the closer the experimental probability will get to the theoretical probability.
