When calculating probability, we are comparing the number of favorable outcomes to the number of possible outcomes. To calculate the probability of the spinner landing on A, C, or D we will use the Probability Formula.
P=Favorable Outcomes/Possible Outcomes
Let's take a look at the spinner.
The spinner has 8 sections, so the number of possible outcomes is 8. Out of these, one section is labeled A, one section is labeled C, and one section is labeled D. The number of favorable outcomes is 3. Now we have enough information to calculate P(red or yellow).
