  2. Contract bridge probabilities - Wikipedia

    en.wikipedia.org/wiki/Contract_bridge_probabilities

    To find the likelihood of a certain point range, one simply subtracts the two relevant cumulative probabilities. So, the likelihood of being dealt a 12-19 HCP hand (ranges inclusive) is the probability of having at most 19 HCP minus the probability of having at most 11 HCP, or: 0.9855 − 0.6518 = 0.3337. [2]

    The probability of this happening is 1 in 13,983,816. The chance of winning can be demonstrated as follows: The first number drawn has a 1 in 49 chance of matching. When the draw comes to the second number, there are now only 48 balls left in the bag, because the balls are drawn without replacement .

  4. Odds algorithm - Wikipedia

    en.wikipedia.org/wiki/Odds_algorithm

    In decision theory, the odds algorithm (or Bruss algorithm) is a mathematical method for computing optimal strategies for a class of problems that belong to the domain of optimal stopping problems.

  5. Probability distribution - Wikipedia

    en.wikipedia.org/wiki/Probability_distribution

    A discrete probability distribution is applicable to the scenarios where the set of possible outcomes is discrete (e.g. a coin toss, a roll of a die) and the probabilities are encoded by a discrete list of the probabilities of the outcomes; in this case the discrete probability distribution is known as probability mass function.

  6. Win probability - Wikipedia

    en.wikipedia.org/wiki/Win_Probability

    The art of estimating win probability involves choosing which pieces of context matter. Baseball win probability estimates often include whether a team is home or away, inning, number of outs, which bases are occupied, and the score difference. Because baseball proceeds batter by batter, each new batter introduces a discrete state.

  7. Birthday problem - Wikipedia

    en.wikipedia.org/wiki/Birthday_problem

    Comparing p(n) = probability of a birthday match with q(n) = probability of matching your birthday. In the birthday problem, neither of the two people is chosen in advance. By contrast, the probability q(n) that at least one other person in a room of n other people has the same birthday as a particular person (for example, you) is given by

  8. Probability of precipitation - Wikipedia

    en.wikipedia.org/wiki/Probability_of_precipitation

    There is also a probability of precipitation for every location in the United States for every minute for the next two hours. This is also known as a minute-cast. This is also known as a minute-cast. The Weather Channel 's definition may include precipitation amounts below 0.01 inch (0.254 mm) and includes the chance of precipitation 3 hours ...

  9. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.
