Question

davis performed an experiment in which he spun a 4 - color spinner 20 times. he recorded his results in the frequency table.
first experiment

color	red	green	blue	purple

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?
yes. another experiment will give the same numbers as the first experiment.
yes. the experimental probabilities remain the same for all experiments.
no. the frequencies will be multiplied by 20.
no. the frequencies and probabilities for red and green segments might change in the next experiment.

Explanation:

Experimental probabilities and frequencies in probability - based experiments are subject to random variation. Just because the frequencies of red and green were equal in one experiment does not mean they will be equal in another. Each spin is an independent event and outcomes can vary.

Answer:

No. The frequencies and probabilities for red and green segments might change in the next experiment.
