B
Returns a probability in a binomial distribution.
Syntax:
B(n; p; s; s2)
- With n independent trials, each with a probability p of success, B returns the probability that the number of successes will be between s and s2 inclusive, or if s2 is omitted the probability that the number of successes will be exactly s.
Example:
B(10; 1/6; 2)
- returns approximately 0.29 (29%), the probability that the number four will be thrown exactly twice in 10 throws of a die.
