The BINOMDIST function returns the individual term binomial distribution probability of the specified form.
BINOMDIST(success-num, trials, prob-success, form-type)
success-num: A number value representing the number of successful trials or tests. success-num must be greater than or equal to 1 and less than or equal to trials.
trials: A number value representing the total number of trials or tests. trials must be greater than or equal to 0.
prob-success: A number value representing the probability of success for each trial or test. prob-success must be greater than or equal to 0 and less than or equal to 1.
form-type: A modal value that indicates which form of the exponential function to provide.
cumulative form (TRUE or 1): Return the value of the cumulative distribution function form (that the specified number or fewer successes or events will occur).
probability mass form (FALSE or 0): Return the value of the probability mass function form (that there are exactly the specified number of successes or events).
Notes
The BINOMDIST function is appropriate for problems with a fixed number of independent trials that have a constant probability of success and where the possible outcomes of a trial are only success or failure.
