Good solution.
If the favorite has win percentage of 1/2 + q where 0 <=q <= .5 and the favorite is equally likely to be the undefeated player as the one loss player then the chance of one loss player winning is average of (1/2 + q)^2 and (1/2 - q)^2 which equals 1/2 + q^2. If q is not exactly 0 this is greater than 1/4.
