4 blue + 5 yellow = 9 total
the probability of picking a blue marble on the first draw is (# of blue)/(# total) = 4/9
no replacements are made, so after the first draw we have 9-1 = 8 marbles left over. There are still 5 yellow marbles
the probability of picking yellow on the second draw is (# of yellow)/(# of marbles left) = 5/8
