Hi, 
15 balls f which 4 are red, 8 are green, and 3 are blue 
With replacement of the first ball
P(first ball is red and the second is green) = 4/15 * 8/15 = 32/225= .142

without replacement (14 total balls in the urn on the second draw)
P(first ball is red and the second is green) = 4/15 * 8/14 = 32/210 = .152
