An urn contains 5 red balls, 3 white balls, and 6 blue balls. Determine the probability that they are drawn in the order of blue, white, and red, given that each ball is NOT replaced in the urn after it is drawn.

6/14 * 3/13 * 5/12 = 15/364

yeah, thats what I get. They come up with a different answer (14/2184). I didn't think I could be wrong cuz its such a simple problem. Its also not the first problem that their answer has been different from mine either, and the fact they don't show the solutions to all the problems is insanely stupid. This things going in the trash. Thanks for making me not feel like a ginormous retard, heh.
