10-38.

Guess what? Another spinner. This time the spinner lands on red half of the time and on green one third of the time. The rest of the time it lands on blue. Homework Help ✎

Draw an area diagram for spinning twice and shade the region that corresponds to getting the same color on both spins, for each of the three colors.

Suppose you know that the spinner landed on the same color twice. What is the probability that that color was green?

Divide the area representing landing on green twice by the total area representing landing on any color twice.
