I use this worksheet in my IB/Precalculus class. It walks the students through some examples of dependent, independent, and mutually-exclusive events, and it has them use formulas and Venn diagrams as well.
I use it 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.
