This worksheet is designed to replace a lecture on the topic of dependent and independent events.
I start out class with a 15-minute "mini-lesson," giving my students some basic examples of what today's lesson will be about: I talk about how the presence of clouds affects the probability of rain, and vice versa, and I also talk about how baldness, though not unique to the male gender, definitely changes the probability that someone is a male. Students can relate to these examples, and so we then get into calculating probabilities, which students find much more challenging.
Once the mini-lesson is over, I have them get to work within their groups on this worksheet.
I use this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions. This is a very challenging assignment, and I have found I have to be extremely vigilant in checking in with student groups to make sure they do not misinterpret what the questions are asking.
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.
Immediately before this worksheet, I use the worksheet named 'Permutations and Combinations Geometry Spring 2014' (http://www.teacherspayteachers.com/Product/Permutations-and-Combinations-Geometry-Spring-2014-1267738
), and immediately after this worksheet, I use the reference sheet named 'Area and Perimeter Formulas Reference Sheet Spring 2014' (http://www.teacherspayteachers.com/Product/Area-and-Perimeter-Formulas-Reference-Sheet-Spring-2014-1267759
