I wrote this worksheet to replace a lecture on geometric probability. Instead of giving my students a lot of examples, I give them the basic formula for geometric probability, (included at the start of this worksheet) and the "helper formula," which often comes in handy:
shaded area + unshaded area = total area
With that information, I set them to work on this activity within cooperative groups, and I circulate to make sure they are getting the purpose of the questions. This generally gives them 45 minutes to an hour to engage in the problems, and I find they get more out of it than simply assigning homework from the text.
The file includes spiral review problems.
This worksheet is intended to be written on directly.
