Probability Predictions and Simulations

The questions on a multiple choice test each have 6 answer choices. Which model can be used to simulate randomly selecting the correct answer on a 20 question multiple choice test?

• rolling a six-sided number cube 6 times

• rolling a six-sided number cube 20 times

• spinning a spinner with 4 equal sized sections 4 times

• choosing 1 marble in a bag of 20 different colored marbles

While standing outside of the school waiting to go home, you notice that 3 out of every 12 students leaving school are on their cell phones.  What is the probability that the next student leaving school will NOT be on his or her cell phone?

• 25%

• 30%

• 75%

• 70%

In a survey, 100 middle school students were asked which social media platform they preferred. The results are shown in the table above.
