An urn contains 5 black marbles and 5 red marbles. If 5 marbles are drawn from the urn without replacement the probability that they are all the same color is
------
Choose a color: 2 ways
Choose 5 of that color: 1 way
Choose 5 randomly = 10C5 = 252
-------------
P(5 black or 5 red) = (2*1)/252 = 1/126
