Experimental Probability

Question 15 • ISP ONLY: Expository Reading and Writing S1 (E4250XX)

Davis predicts that if he spins the spinner another 20 times, the frequency for the red and green segments will still be equal. Is Davis correct?

Answer
A
Yes. Another experiment will give the same numbers as the first experiment.
B
Yes. The experimental probabilities remain the same for all experiments.
C
No. The frequencies will be multiplied by 20.
D
No. The frequencies and probabilities for red and green segments might change in the next experiment.

Explanation

Davis cannot know that the red and green frequencies will remain equal. Results in a new set of spins can vary, so the frequencies—and the experimental probabilities based on them—might change. Choice D correctly describes this; another experiment is not guaranteed to repeat the same numbers.
