Question

Hudson is performing an experiment by tossing a paper cup into the air and recording how it lands. He determines that there are three possible outcomes for how the cup will land: on its top, on its bottom, or on its side. He is curious if the three outcomes are equally likely. The table below shows the results of Hudson's experiment.
Outcome Frequency
Top 4
Bottom 1
Side 25

a. What is the approximate probability that on the next toss, the paper cup will land on its top? On its bottom? On its side? Express each answer as a percentage.
b. From the results of Hudson's experiment, do the three outcomes appear to be equally likely? Explain your reasoning using complete sentences.

Answer 1

It has landed on its side 25/30 times, on the top 4/30 times 25/30=5/6,1/30=0.2/6 and 4/30=0.8/6.
