What is the probability that it will not be black?
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.
