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 Geometry 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.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
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 personalize for your students.
