The spinners at right are spun and the results are added.  

1. Find $\text{P}(\text{sum is }4)$.

   Hint (a):

   Draw an area model or tree diagram.

2. Find $\text{P}(\text{sum is }8)$.

   Hint (b):

   Using the area model or tree diagram you made in part (a), circle all the places on your model where the sum is $8$.

   Answer (b):

   $P(\text{sum is }8)=\frac{1}{12}+\frac{1}{4}=\frac{1}{3}$
