Question 118740: Suppose you have a bag that contains 4 black, 3 green, 1 red, and 2 orange marbles. Find each probability.

Thanks this question is hard, by the way P means probability
P(red 1st AND orange 2nd) = P(red 1st) x P(orange 2nd) =

%281%2F10%29x%282%2F9%29

cancel the 2 into the 10, getting 5 on the bottom:

         1
%281%2Fcross%2810%29%29x%28cross%282%29%2F9%29
  5

1%2F45
