This is a bonus post for my main post on the binomial distribution. Here I want to give a formal proof for the binomial distribution mean and variance formulas I previously showed you.

Hi, everyone! And welcome to my post about the binomial distribution! Just like the Bernoulli distribution, this is one of the most commonly used and important discrete probability distributions.

## The Bernoulli Distribution: Intuitive Understanding

In today’s post, I’m going to give you intuition about the Bernoulli distribution. This is one of the simplest and yet most famous discrete probability distributions. Not only that, it is the basis of many other more complex distributions.

## The Birth and Evolution of Cryptographic Codes

Welcome to part 4 of my series on cryptography! After taking an in-depth look into ciphers in the previous two posts, now it’s time to delve into the other big category of cryptographic methods. So, this week’s post is going to be about cryptographic codes.

## Vigenère and the Age of Polyalphabetic Ciphers

In this week’s post, I’m going to introduce you to the world of polyalphabetic substitution ciphers. And to the most famous cipher from this category: the Vigenère cipher.

## The Column and Caesar Ciphers: Ancient Cryptography

Today, I’m going to introduce two ciphers from the dawn of cryptography: the column cipher and the Caesar cipher. These ciphers illustrate some of the first human ideas in the direction of cryptographic thought.
