I know this to be true but there is some part of me that wonders whether I would bet against the person who says that out of a hundred tosses at least one of them will be heads and at least on of them will be tails. Seems that there must be some other level of probability that could be determined. The odds for tossing 100 straight heads or 100 straight tails could not be the same as tossing 50 heads and 50 tails. Could it? Seems improbable... <g>
