A game involves conducting an experiment and gathering data to find the experimental probability of an event. What is a good first step for finding the experimental probability of an event?

• Make a square to show an area model and then divide the sections in equal sections.

• Determine the outcomes of the event and make a table to record results.

• Multiply the probability of the first event and the probability of the second event.

• Make a table to show results and divide the results in equal amounts according to the outcomes.
