X total number of successes pass or fail heads or tails etc P probability of a success on an individual trial. Binomial distribution is a discrete probability distribution which expresses the probability of one set of two alternatives-successes p and failure q. So r 60 060.
In general for the expansion of x yn on the right side in the n th row numbered so that the top row is the 0th row.
N is the fixed number of trials. The binomial distribution is a common way to test the distribution and it is frequently used in statistics. N it stands for the number of times the experiment is conducted p represents the possibility of one specific outcome. X total number of successes pass or fail heads or tails etc P probability of a success on an individual trial.
