• 2 R, 3 B, 4 G, => 9 total
  Probability that Nikki picks green = 4/9.
  
  Now, 2 R, 3 B, 3 G => 8 total
  Probability that Tom picks blue = 3/8
  
  Probability that Mary picks a blue=1/7.
  Both together, multiply the probabilities.
  
  probability that Niki will draw a green marble and Tom will draw a blue marble = ( 4/9 ) * ( 3/8 ) = 1/6
