## Equally Likely Outcomes - Multi Scenario Combination Tennis Balls

A bucket containing orange tennis balls and yellow tennis balls from which 5 balls are selected at random, but assume that the bucket contains 7 orange balls and 6 yellow balls.

(1) What is the probability that, of the 5 balls selected at random,
at least one is orange and at least one is yellow?

(2) What is the probability that, of the 5 balls selected at random,
at least two are orange and at least two are yellow?
