What is probability of:
a) both balls are in different colors
b) both balls are in same color

a) both balls are in different colors Exactly what type of outcomes will satisfy this?
b) both balls are in same color Exactly what type of outcomes will satisfy this?

Before you can do such a problem you must be able to answer the questions above. In doing so it is best talking about the outcome of the first and 2nd pick.
