I'm not sure what form of tree diagram you are expected to produceOriginally Posted byMary Cluck

but the attached figure shows one type of tree diagram for this

problem.

The number of outcomes is equal to the number of leaf nodes on the2. How many outcomes are there if you draw a ball from boxes 1 and 2?

Any help appreciated---

diagram (in this case nodes on the right), which in this case is 12.
