If everything is fair and we toss a coin then probability of having head or tail is “1/2”. Well!! If we extend our experiment say to toss the coin 100 times. As a result, will we get 50 heads and 50 tails? Common sense says that most of the time, we don’t have exactly 50 heads. Even further labor up to 1000 times of tossing; still we don’t get exactly 500 tails or 500 heads. Then why it is TRUE that every time, while tossing a coin we say that probability of getting head or tail is “1/2”?
