Conditional Probability and Tree Diagrams with Answer Key (Editable)

Once I've covered basic probability and statistical measures, I like to have students work with conditional probability, which can often go hand-in-hand with tree diagrams. I created this worksheet for my Algebra 1 students, and I find that it is challenging for them, but it can be broken down into "baby steps" and they learn to navigate their way around a tree diagram to calculate conditional probabilities.

The file includes spiral review problems. Note: "Number cube" is the preferred term on standardized tests instead of "die" or "dice."

This worksheet is intended for students to show their work on a separate sheet of paper.

Please download the pdf preview file first, so you can see exactly what's included; the product file is a word document, which you may edit for your students.
