a.) describe the sample space N(S)

b.) What is the probability of drawing a green marble on the second draw?

c.) What is the probability of drawing two marbles with numbers that sum to an odd value?

d) what is the conditional probability of drawing a red marble on the first draw, given that an odd numbered marble was drawn on the second draw?

e.) what is the conditional probability of drawing a blue marble on the second draw, given that the sum of the numbers on the two marbles is equal to 3?
