# Binomial Random Variable

Binomial random variable is a discrete random variable which is related to Binomial experiments or Bernoulli trials. Experiments whose outcomes can be reduced to two outcomes as success and failure are called Binomial experiments. For example, a multiple choice question can have five options. But the outcome of attempting the question turns out to be either right or wrong, which can be treated as success and failure. If there are 10 such questions in a test and a student just selects the options guessing, then the Binomial random variable here can denote the number of questions which he got right.
