The result is not clearly significant

If you give 2 equal programs to play 200 games and if you assume that the
probability for white to win is 40% and that the probability for black to win is
30%
then the probability of a result of at least 110:90 for one side is close to 10%

The probability of a result at least 110:90 for chessmaster 6555 is close to 5%
assuming that the programs are equal and the same for a result of at least
110:90 for chessmaster6000.
