Probability Word Problems Middle School Probability of Compound Events

This middle school (grades 6-8) probability lesson and worksheet has three parts to help your class understand the probability of compound events (2 events that both occur but do not affect one another) and how to write probabilities as decimals and percentages.

How it Works:

There are two "casino games" presented. Each has two steps and specific rules.

1) Students first determine the theoretical probability (in fractions, decimals, or percents) of the casino game that has a spinner and a die and three different outcomes.

2) Students next determine the theoretical probability (in fractions, decimals or percents) of the casino game that has a penny and a die and three different outcomes.

3) Finally, students will compare the two games and pick which game they would choose to play using their math calculations as justification.

Students can use fractions, decimals, or percents to figure out the theoretical probabilities from these two games. They will notice that all the outcomes in one game will always add to 1.00 or 100%

This lesson is specifically created to target 7th Grade Statistics Learning Outcomes 7.SP.C.5 and 7.SP.C.8
