100! = 100*99*98...3*2*1\n\nSources of zeroes are multiples of five and multiples of 10:\n10, 20, 30, ... (10 to 90 and 100, 11 zeroes)\n5*2, 25*2, ... (5, 15, 25... 95, will make 10 zeroes)\n25, 50, 75 (another 3 zeroes)\nSo I guess it should be total 24 zeroes.

3% equals .03 which are the bad, and 1.00 is 100% so u subtract .03 from 1 to get .97 which are the good
