Yes :) The exact probability for having 50%/50% is (100 nCr 50)/2^100, or about (as you found through experiemtation) 0.08. The more often you run the experiem

Yes :) The exact probability for having 50%/50% is (100 nCr 50)/2^100, or about (as you found through experiemtation) 0.08. The more often you run the experiement, the more likely you'll get a result close to 50%/50%, by the way. In the limit, you have a variance (i.e. spread of results away from the expected value, which is 50%) of 0. This is called the law of large numbers. As the generic name suggest, it's pretty central to mathematics haha.
