The spinner at right is spun twice. Calculate the probability of each of the following outcomes.

1. Getting black twice.

   Hint (a):

   What is the probability of getting black once? Multiply that by itself to find the probability of getting black twice.

   Answer (a):

   $\left(\frac{1}{3}\right)\left(\frac{1}{3}\right)=\frac{1}{9}$

2. Getting green twice.

   Hint (b):

   Is it any more or less likely that someone will get green over black?
