Pick a Card

This Instructional Activity is a part of the Lesson 9, Unit 8, Grade 7. In this activity, students see an experiment that has two steps where the result of the first step influences the possibilities for the second step. Often this process is referred to as doing something "without replacement." At this stage, students should approach these experiments in a very similar way to all of the other probability questions they have encountered, but they must be very careful about the number of outcomes in the sample space.
