The document discusses using tree diagrams and area models to calculate probabilities of outcomes when spinning two spinners. There are 12 total outcomes when spinning one spinner then the other. The probability of each individual outcome is 1/12. The probability of getting the same color on both spinners is 1/6.

2. What is the probability of each outcome? To answer these questions, you first need to find a way to organize all possible outcomes. If you were to spin Spinner A once and then Spinner B once, how many outcomes exist? Spinner A Spinner B
