Maybe this one isn't that hard if you know combinatorics but it took me quite some time and graphing.
If you have 100 coins and you flip all of them, what's the probability that exactly 50 land heads up and 50 land tails up?
Bonus - Create a formula which finds the answer for the above question but instead of 100 coins, it's any number of even coins ie '2n'.
