Kendra has 5 red marbles, 4 blue marbles, and 3 white marbles. What is the probability that she draws a red marble and then a blue marble without replacing the first marble? *

Total 12 marbles    5 are red       5/12   chance red on first draw

    now there are 11 marbles left   4 are blue    4/11 chance blue on second draw

 

5/12 * 4/11 = .........
