@mvnla2 @kerravon @jamairoqui @burbman Here calculations of the 95% chance frequency interval (you have a probability of 0.95 that the number of tails fall in this interval) for some numbers of coin tosses (I suppose that the probability is 0.5)
10 tosses -> 0.5±1/sqrt(10) -> [18.4% , 81.6%]
20 tosses -> 0.5±1/sqrt(20) -> [27.6% , 72.4%]
50 tosses -> 0.5±1/sqrt(50) -> [35.9% , 64.1%]
100 tosses -> 0.5±1/sqrt(100) -> [40.0% , 60.0%]
200 tosses -> 0.5±1/sqrt(200) -> [42.9% , 57.1%]
500 tosses -> 0.5±1/sqrt(500) -> [45.5% , 54.5%]
1000 tosses -> 0.5±1/sqrt(1000) -> [46.8% , 53.2%]
