Probability is literally how AI thinks and makes every decision! 🤖

ChatGPT generates each word by picking the highest-probability next token from millions of options. Spam filters use Bayesian probability to detect junk mail. Weather apps say "70% rain" using probabilistic simulation models.

Conditional probability (P(A|B)): The probability of A GIVEN that B has already happened. Example: given that it's raining, what's the probability of traffic? That's conditional — and it powers every recommendation algorithm.

Exam shortcut — "at least one" problems: P(at least one) = 1 − P(none). MUCH easier to calculate from the complement. Don't enumerate all cases!

BGMI / poker connection: When you calculate the probability of finding a Level 3 helmet in a specific drop zone, you're doing applied probability without realising it.
