Top Probability Flashcards

Probability means chance - it's a branch of math that studies how likely something is. If you reach your hand into a box of red-and-white superballs, what is the chance that you will pick out a red one? Probability helps us answer these sorts of questions. It starts from a few basic measurements – like how many balls are in the box and how they are arranged inside – and uses them to make predictions about the result.


We live in a world full of random, unpredictable outcomes, and every day we use probability to figure out how we should get by in that world. Should you bring an umbrella from home? It depends on the probability of rain. Should you buy a lottery ticket? It depends on the probability of winning. While other branches of math are more cut-and-dried, probability is all about unpredictable situations and cases where you can never know for sure what the outcome will be.
