Is it possible that in an endless game of heads and tails, tails will not appear even once?
Well, that is, let's say you tossed a coin 10 times, and all 10 times an eagle fell out. You decide to flip the coin 100 more times, and lo and behold, a hundred eagles again. When you have the courage to throw a coin an infinite number of times, can it never show tails? Or is it necessary that both heads and tails appear an infinite number of times?
