# What is an example of a binomial expression?

A binomial expression is an algebraic expression consisting of two terms or monomials separated by a plus (+) or minus (−) sign. Examples of binomials include: ax + b, x2 − y2, and 2x + 3y. In Algebra, you are often required to multiply expressions together.

Correspondingly, what is the binomial distribution formula?

This makes Figure 1 an example of a binomial distribution. The formula for the binomial distribution is shown below: where P(x) is the probability of x successes out of N trials, N is the number of trials, and π is the probability of success on a given trial.

What is the formula for combinations?

A formula for the number of possible combinations of r objects from a set of n objects. Formula: Note: , where nPr is the formula for permutations of n objects taken r at a time.

Who made the binomial theorem?

However, the pattern of numbers was already known to the European mathematicians of the late Renaissance, including Stifel, Niccolò Fontana Tartaglia, and Simon Stevin. Isaac Newton is generally credited with the generalized binomial theorem, valid for any rational exponent.
