BINOMDIST
Calculates probabilities for a binomial distribution.
Syntax:
BINOMDIST(k; n; p; mode)
- With n independent trials, each with a probability p of success, BINOMDIST returns the probability that the number of successes will be
- exactly k if mode is 0.
- up to (and including) k if mode is 1.
- In other words, BINOMDIST returns the probability mass function if mode is 0, and the cumulative probability function if mode is 1.
- BINOMDIST(k; n; p; 0) is equivalent to B(n; p; k); BINOMDIST(k; n; p; 1) is equivalent to B(n; p; 0; k). See * B for more details.
Example:
BINOMDIST(3; 12; 0.5; 0)
- returns approximately 0.05 (5%), the probability that heads will come up exactly 3 times in 12 flips of a coin.
BINOMDIST(3; 12; 0.5; 1)
- returns approximately 0.07 (7%), the probability that heads will come up 0, 1, 2 or 3 times in 12 flips of a coin.
