Common Errors• Exercises 6–11 Students may forget to include, or include too many,

favorable outcomes. Encourage them to write out all of the possible outcomes and then circle the favorable outcomes for the given event.

• Exercises 12–17 Students may forget to include the repeats of a color when describing the favorable outcomes and how many ways the event can occur. Ask students to describe how many times you could pull out a specifi c color from the bag if you happened to pull out the same color each time (without replacing). For example, if the event is choosing a red marble, you can pull out a red marble three times before there are no more red marbles in the bag. So, the event can occur three times.
