Summary
Probability is the study of how likely events are to happen. Students learn how to calculate the chance of an event, and get examples of probability in real life.
What Is Probability
Probability is a way to measure how likely something is to happen. It has two main parts: the event you are interested in, and the sample space, which is all possible outcomes.
Calculating Probability
Probability is calculated by dividing the number of successful outcomes by the total number of possible outcomes. Examples show how to do this for different situations.
Probability In Real Life
Probability is used in many real-life situations. Examples include dividing a stake in a game and calculating the chance of winning a lottery.
Coin Flipping Probability
The document explains how to calculate the probability of flipping a coin and getting heads a certain number of times. It compares this to weather forecasting.
