Probability and statistics play a vital role in mathematics, finance, economics, engineering, data science, and scientific research.
A discrete random variable takes countable outcomes: the number of heads in two coin tosses, the defects in a batch, the goals in a match.
Probability tells you how likely an event is, and a percentage tells you at a glance.
A Poisson model answers one question: if events happen at a steady average rate, how likely is a particular count in the next interval?
Roll the same dice long enough and the totals settle around one number: the expected average.
The negative binomial distribution answers a waiting question: how many failures should you expect before the r-th success, or how many trials will that take in total?
Flip a coin 10 times and exactly 6 heads feels like it should be common, yet it happens only about one time in five.
The binomial coefficient C(n, k), read “n choose k,” counts how many ways you can pick k items from a set of n when the order of the pick does not matter.
A positive test, a turned card, a signed contract: once one event has happened, every other probability changes.
An average tells you where a distribution sits. It says nothing about how tightly it sits there once you learn something.
