Question 837542
A bag contains 3 red marbles, 5 green marbles, and 2 blue marbles. Two consecutive draws are made from the bag(without replacement of the first draw).    Find the probability of each event:               a. P(red,blue)             b. P(blue,blue)           c. P(red,not red)
<pre>
P(red 1st then blue 2nd) = {{{(3/10)(2/9)}}} = {{{6/90}}} = {{{1/15}}}

P(blue 1st then blue 2nd) = {{{(2/10)(1/9)}}} = {{{2/90}}} = {{{1/45}}}

P(red 1st then not red 2nd) = {{{(3/10)(7/9)}}} = {{{21/90}}} = {{{7/30}}}
