Bridge Probabilities - Probability of Suit Distributions in Two Hidden Hands

Probability of Suit Distributions in Two Hidden Hands

This table represents the different ways that two to thirteen particular cards may be distributed, or may lie or split, between two unknown 13-card hands (before the bidding and play, or a priori).

The table also shows the number of combinations of particular cards that match any numerical split and the probabilities for each combination.

These probabilities follow directly from the law of Vacant Places.

Famous quotes containing the words probability of, probability, suit, hidden and/or hands:

    The probability of learning something unusual from a newspaper is far greater than that of experiencing it; in other words, it is in the realm of the abstract that the more important things happen in these times, and it is the unimportant that happens in real life.
    Robert Musil (1880–1942)

    The probability of learning something unusual from a newspaper is far greater than that of experiencing it; in other words, it is in the realm of the abstract that the more important things happen in these times, and it is the unimportant that happens in real life.
    Robert Musil (1880–1942)

    Selflessness is like waiting in a hospital
    In a badly-fitting suit on a cold wet morning.
    Selfishness is like listening to good jazz
    With drinks for further orders and a huge fire.
    Philip Larkin (1922–1986)

    Nobody knows what the cause is,
    Though some pretend they do;
    It’s like some hidden assassin
    Waiting to strike at you.
    Childless women get it,
    And men when they retire;
    It’s as if there had to be some outlet
    For their foiled creative fire.
    —W.H. (Wystan Hugh)

    The ball loved Flick.
    I saw him rack up thirty-eight or forty
    In one home game. His hands were like wild birds.
    John Updike (b. 1932)
