To find the solution, describe the events that will allow the same color draws which are WW or BB or YY. Since replacement is not stated, without replacement is assumed. So, we need probability of WW, BB, and YY (added together) which are (2/12*1/11) + (4/12*3/11) + (6/12*5/11) or (2/132 + 12/132 + 30/132) or 44/132 or1/3.

That would be based upon the remainder of the probability it could be anything else, depending upon all of the other choices (red, white, yellow, Caucasian...). For example, if there is a 99 percent chance it's white, and the only two choices are white or black, and there are no external constraints that prevent it from being less than random, there would be a 1 percent probability it would be black.
