Question 118740
Suppose you have a bag that contains 4 black, 3 green, 1 red, and 2 orange marbles. Find each probability. 
P(red, then orange when red is not replaced) 
Thanks this question is hard, by the way P means probability
<pre>
P(red 1st AND orange 2nd) = P(red 1st) x P(orange 2nd) =

{{{(1/10)}}}x{{{(2/9)}}}

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

         1
{{{(1/cross(10))}}}x{{{(cross(2)/9)}}}
  5

{{{1/45}}}
