Hi everyone(adsbygoogle = window.adsbygoogle || []).push({});

There is a question which I find very hard to solve and it goes like this..

A symmetric coin with heads on one side and tails on the other side is tossed 491 times after one another. The total amount of times you get tails is either even or odd. Is the probability that you get an even amount of tails exactly 50%? And the question requires a strong mathematical evidence, e.g. a formula.
