So the probability of a success of 4 or more heads in a row for every 10 coin flips is 251/1,024 = 0. If that event is repeated ten thousand different times, it is. Even unlikely events happen given enough opportunities. That is because each time you flip the coin, the odds remain 1/2; the two flips are independent of each other. Basically, I calculate if the current flip in a 10 flip session is equal to the prior flip, and if it is, I increment a counter. Jacque Wilson, in a piece for CNN titled: Calculating the odds: 12 sons in a row reports the odds at about 1 in 4000. Because of all the random factors beyond our control that enter the flipping process (force with which the coin is flipped, motion of the air in the room, position of our hand when we catch the coin) we therefore expect a probability of 1/2 for heads, and 1/2 for tails. game theory written in collaboration with Oskar Morgenstern entitled Theory of Games and Economic Behavior, 1944.
