Notice that we can treat outcomes A and B as one outcome that is opposite to our favorable outcome.
Yes, see solution.
Practice makes perfect
We are given that an experiment has 3 equally likely outcomes: A, B, and C. If we would like to use a spinner to simulate this experiment, then we should divide our spinner into 3 congruent regions. Each of these regions should have a central angle that measures 360^(∘)3=120^(∘).
However, if we are interested only in predicting the probability of outcome C, we can combine the regions that represent outcomes A and B. Let's shade them using one color.
Therefore we could use the spinner shown in a simulation to predict the probability of outcome C.
