Compound Event Probability With Tree Diagrams
Written by Adi Ackerman, Head Teacher
"Compound Event Probability With Tree Diagrams" is written for 7th Grade (Ages 12-13), and it covers Common Core 7.SP.C.8.A. A 6th grader who is already steady on probability can use it too, and an older student can use it as a short review.

7th grade math worksheet: use tree diagrams for a coin and spinner and for two spins of an R, B, Y spinner. Answer key included. Part of our compound events probability collection. Aligned to Common Core standards.
How do I use this worksheet?
Do the sample space sheet first, then tree diagrams, then the simulation sheets. The carnival game suits a project day.
What students will practice
- Students will read tree diagrams that show every outcome of a compound event.
- Students will find probabilities of compound events in simplest form.
- Students will complete the empty boxes on trees before finding probabilities.

Standard: Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.

FAQ
How do I use this compound events worksheet?
⌄
Do the sample space sheet first, then tree diagrams, then the simulation sheets. The carnival game suits a project day.
What does this worksheet teach?
⌄
Use tree diagrams for a coin and spinner and for two spins of an R, B, Y spinner. The directions on the page read: All outcomes are equally likely. Use each tree diagram to find the probabilities in simplest form. Fill in the empty boxes on trees 3 and 4 first. An answer key is included.
Can I use this compound events worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade probability, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What is a compound event?
⌄
A compound event has more than one part, such as a coin flip and a number cube roll. Students list all the outcomes to find its probability.
How does a simulation estimate a probability?
⌄
A simulation uses a coin, number cube or random digits to stand for the events. Students run trials, count the successes and divide. The Simulate Compound Events With a Random Table worksheet gives printed digits.
What do the simulation sheets need?
⌄
The simulation design sheet needs a coin and a number cube. The random table sheet uses printed digits and needs no tools.
Do these worksheets have answer keys?
⌄
Yes. All 6 worksheets in this group have answer keys.
