You need to know how to find probabilities of binomial variables using simulation data or your calculator. Using random number generators is crucial.

A **binomial setting **arises when we perform *n* independent trials of the same chance process and count the number of times that a particular outcome called a success, occurs. Failure is defined as 1 minus the probability of success.

The count of successes in a** binomial setting** is a** binomial random variable**. The probability distribution of X is a binomial distribution. The possible values of X are 0, 1, 2, 3, …,n. Any **binomial distribution** is completely specified by two numbers: the number of trials of the chance process and the probability p of success on each trial.

To find binomial variable probability, use the following formula or use the calculator function of **binomCDF/PDF.**
