What is probability?

Probability is like guessing which candy you’ll get from a jar, some are more common than others.

Imagine you have a big bowl full of red and blue jellybeans. If there are 10 red ones and only 2 blue ones, it’s more likely you’ll pick a red one because there are more of them in the bowl. That's probability, it helps us understand how likely something is to happen.

Probability uses numbers from 0 to 1. If something is impossible, its chance is 0, like picking a green jellybean when all the candies are red and blue. If something is certain, its chance is 1, like always getting a red jellybean if only red ones are in the bowl.

We use probability every day, like when we decide whether to bring an umbrella because there's a chance it will rain. Or when we roll dice and guess what number might come up next.

Probability is just a way of saying “how likely” something is, based on how often it happens. It’s not magic, it's just counting and guessing with numbers! Probability is like guessing which candy you’ll get from a jar, some are more common than others.
