## Is combinatorics useful for probability?

Combinatorics is especially useful in computer science. Combinatorics is also important for the study of discrete probability. Combinatorics methods can be used to count possible outcomes in a uniform probability experiment.

**How are combinatorics used in statistics and probability?**

Combinatorics and Statistics Since combinatorics gives us answers to question about the number of possible outcomes we have when picking subsets from larger sets, combinatorics is also important when designing research projects or studies in social sciences. It forms the groundwork for many probability problems.

**What is the formula of combinatorics?**

Number of permutations of n objects: n! Number of ordered samples of size r, with replacement, from n objects: nr • Number of ordered samples of size r, without replacement, from n objects: n(n − 1)···(n − r + 1) = n!

### Where are combinatorics used?

Combinatorics is applied in most of the areas such as: Communication networks, cryptography and network security. Computational molecular biology. Computer architecture.

**Who discovered combinatorics?**

In the West, combinatorics may be considered to begin in the 17th century with Blaise Pascal and Pierre de Fermat, both of France, who discovered many classical combinatorial results in connection with the development of the theory of probability.

**Who is the father of combinatorics?**

The Swiss mathematician Leonhard Euler was finally responsible for the development of a school of authentic combinatorial mathematics beginning in the 18th century. He became the father of graph theory when he settled the Königsberg bridge problem, and his famous conjecture on Latin squares was not resolved until 1959.

## What combinatorics means?

Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures.

**How to combine two probabilities?**

– Vote Using Mean Probabilities – Vote Using Sum Probabilities – Vote Using Weighted Sum Probabilities

**Do data scientists use combinatorics or discrete probability?**

To understand how this works, you need to use concepts from calculus: gradient, derivatives, limits, and chain rule. This area is not discussed as often in data science, but all modern data science is done with the help of computational systems, and discrete math is at the heart of such systems.

### What exactly is combinatorics?

Combinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures.It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from evolutionary biology to computer science.. The full scope of combinatorics is not universally

**What are some practical applications of combinatorics?**

the enumeration (counting) of specified structures,sometimes referred to as arrangements or configurations in a very general sense,associated with finite systems,
