Understanding Probability Concepts

This video tutorial introduces the concept of probability, explaining how it measures the likelihood of events occurring. It covers the probability formula, which is the ratio of favorable outcomes to the total possible outcomes. The tutorial provides practical examples using a coin toss and a dice roll to illustrate how to calculate probabilities. The video also discusses different ways to express probability results, such as fractions, decimals, and percentages.

What is the main purpose of probability?

• To predict future events with certainty

• To measure the chance of a specific event occurring

• To eliminate randomness in experiments

• To ensure all outcomes are equally likely
