The standard deviation of the sampling distribution of counts for sample size 24000 is $\sqrt{24000 x 0.5 x 0.5}$ That is, about 48% of all samples of size 24000 will yield a count of heads between 11950 and 12950. And, 95% of sample proportions will be between .494 and .506. That's due to the CLT.

I just asked my computer to flip the coins and got 11,996. How else would the LLN work? Aug8 comment How to determine if coin comes up heads more often than tails? @Pete I did not suggest that the set of people who flipped a coin many times to be limited to the three I mentioned. Those are the ones that I know are documented. However, I hope you would agree that FEW would be the appropriate adjective to describe the number of people who have tossed the same coin repeatedly that many times. I used to assign a homework where students were required to toss a coin 20-30 times. I know most of them could not be bothered with that.
