The binomial distribution represents the probability for 'x' successes of an experiment in 'n' trials, given a success probability 'p' for each trial at the experiment. If the probability of success on an individual trial is p , then the binomial probability is n C x ⋅ p x ⋅ ( 1 − p) n − x . Since these problems were researched by Swiss mathematician Jacques Bernoulli around 1700, they are also called Bernoulli trials . The 1 is the number of opposite choices, so it is: n−k. If the probability of success pin each trial is a fixed value and the result of each trial is independent of any previous trial, then we can use the binomial distributionto compute the probability of observing xsuccesses in ntrials. ( p) is an indicator bernoulli variable which is 1 if experiment i is a success. To generate a binomial probability distribution, we simply use the binomial probability density function command without specifying an x value.
