A bag contains four red, three green, and five yellow marbles. three marbles are drawn, one at time, without replacement. Determine the probability that the probability that the order in which they are selected is:
a) P(yellow, red, green) = 5/12 * 4/11 * 3/10 = 60/(12*11*10) = 1/22
------------------------------------------
b) P(yellow, yellow, red) = (5/12)(4/11)(4/10) = 80/(12*11*10) = 1/66
-----------------------------------------
I'll leave this to you:::
c) yellow, green, green
