  • Binomial Probability

    Chance of observing a specific number of successes in repeated independent trials with constant success probability.
  • BINOM.DIST Function

    Excel tool for calculating exact or cumulative binomial probabilities using four required arguments.
  • Argument

    Input value required by a function, such as number of successes, trials, probability, or cumulative option.
  • Number of Successes

    Count of desired successful outcomes in a binomial experiment, often denoted as x.
  • Number of Trials

    Total count of independent attempts or events in a binomial setting, commonly represented as n.
  • Probability of Success

    Likelihood that a single trial results in a successful outcome, typically expressed as a decimal.
  • Exact Probability

    Chance that the number of successes matches a specific value, calculated with cumulative set to false.
  • Cumulative Probability

    Chance that the number of successes is less than or equal to a specified value, calculated with cumulative set to true.
  • Complement Rule

    Method for finding probabilities by subtracting the probability of an event's complement from one.
  • Formula Bar

    Excel interface area where functions and calculations are entered or edited.
  • Cell Reference

    Excel notation indicating the location of a value or formula within a worksheet, used in calculations.
  • Sanity Check

    Quick verification step to ensure calculated probabilities are logical, such as confirming complements sum to one.
  • Decimal Equivalent

    Numeric representation of a percentage used for probability calculations, such as 0.92 for 92%.
  • Business Analytics

    Application of statistical methods, including binomial probability, to inform business decision-making.
  • Statistical Inference

    Process of drawing conclusions about populations based on sample data, often using probability calculations.
