2.3 Introduction to probability
Introduction to Probability
Start probability the right way: learn sample spaces, events, and the basic probability formula through clear, step-by-step examples.
What You'll Learn
Define probability as a number between 0 and 1 that measures how likely an event is to occur.
Identify the sample space of an experiment and list every possible outcome.
Apply the basic probability formula by dividing favorable outcomes by total outcomes.
Recognize that the probabilities of all outcomes in a sample space must add up to 1.
Calculate the probability of a complement using the rule P(not A) equals 1 minus P(A).
Compare theoretical predictions with real experimental results to check reasonableness.
