    The payoffs are provided in the interior. The first number is the payoff received by the row player (Player 1 in our example); the second is the payoff for the column player (Player 2 in our example). Suppose that Player 1 plays Up and that Player 2 plays Left. Then Player 1 gets a payoff of 4, and Player 2 gets 3.

  8. Infinite monkey theorem - Wikipedia

    en.wikipedia.org/wiki/Infinite_monkey_theorem

    For n = 1 million, X n is roughly 0.9999, but for n = 10 billion X n is roughly 0.53 and for n = 100 billion it is roughly 0.0017. As n approaches infinity, the probability X n approaches zero; that is, by making n large enough, X n can be made as small as is desired, [ 3 ] and the chance of typing banana approaches 100%.
