93.75% Chance for your coin flips to be successful. Math is not my strong side, but if 93.75% + 5% = 98.75%. That means you will always have a 1.25% chance to not hit your coin flips on your side of choosing. Well considering it's only 1.25% that is pretty much 0% right? Unless your just a really unlucky person and you for some reason will land on those 1.25% chances many times.
