Making Predictions: Theoretical and Experimental Probability

The table provided represents the number of students wearing different types of athletic shoes in Ms. Smith’s class. If there are 200 students in the courtyard during passing period, predict how many of those students would be wearing Converse.

• 50

• 90

• 60

• 40

The sides of a regular decahedron (a 10-sided shape) are numbered 1 – 10. Nick will roll the decahedron 400 times and predicts that he will roll an 8 or greater 150 times. How does his prediction compare to the theoretical probability?

• His prediction and the theoretical probability match.

• His prediction is higher than the theoretical probability.

• His prediction is lower than the theoretical probability.

Fifteen gumballs were selected from a gumball machine. The results are shown in the table provided. Dana predicts that if an additional 150 gumballs are pulled from the machine, 20 of them would be purple. How does her experimental data compare to her prediction?

• Her prediction and experimental data match.

• Her prediction is higher than the experimental data.

• Her prediction is lower than the experimental data.

A bag contains 5 blue marbles, 10 purple marbles, 6 red marbles, and 9 yellow marbles. What is the probability you will pull a red marble?

• 1/6

• 1/3

• 9/30
