Steve has 8 Orange marbles and 4 purple marbles in a jar. He draws two marbles from the jar without replacing the first marble.
What is the probability of the orange marble and a purple marble on his second draw

P (orange on first draw  and  purple  on second)  =  (8/12 ) * (4/11)  = (2/3) * ( 4/11)  = 8 / 33
