Feller's coin-tossing constants

Okay kiddo, have you ever played coin-tossing with your friends or family? You know, when you flip a coin and call heads or tails? Well, Feller's coin-tossing constants is a fancy name for how many times you need to flip the coin to get a certain pattern.

Let's say you want to get 3 heads in a row. That means you need to flip the coin a certain amount of times until you get 3 heads in a row. Feller's constant can tell you the average amount of times you need to flip the coin until you get that pattern.

But why is this important? Well, sometimes in science or math, people need to know the probability of getting a certain pattern when they flip a coin. Feller's constant can help them figure out that probability.

So, to sum it up, Feller's coin-tossing constants tells us how many times we need to flip a coin on average to get a certain pattern, which can help us figure out the probability of getting that pattern.
