When playingTexas Hold 'empoker, each hand starts with each player being dealt two cards from a randomly-ordered deck. If a player's two cards are of the same rank (e.g., two 7s, or two Queens) then he is said to have been dealt a "pocket pair." Suppose that a player plays 170 hands ofTexas Hold 'em. LettingYbe the number of times he is dealt pocket pairs, use the normal approximation (with a continuity correction) to approximate the value ofP(Y < E(Y)).
