A container has 4 green balls, and 9 yellow balls. A ball is selected at random from the container, its color is noted and it is NOT replaced. A second ball is selected and its color is noted.

(a) What is the probability that the neither of the balls selected is green?

(b) What is the probability that the balls selected are of the same color?

(c) What is the probability that exactly one of the balls selected is green?

(d) If we know the first ball is yellow, what is the probability that the second ball selected is green?

(e) What is the probability that the first ball selected is green and the second ball is yellow?
