Probability Explained | Basic Concepts, Tree diagram, formula & Worked Examples Part 1 by Mr Stephen

Описание: In this video, you will learn Probability from the basics in a simple and easy-to-understand way. This lesson is perfect for secondary school, high school, and beginner mathematics students, as well as anyone preparing for exams that include probability questions.

Probability is a branch of mathematics that deals with chance and uncertainty. It helps us measure how likely an event is to happen. In everyday life, probability is used in areas such as games, weather forecasting, statistics, finance, insurance, and decision making. In this lesson, we explain probability step by step using clear definitions and worked examples.

🔹 What You Will Learn in This Video

✔ Meaning and definition of probability
✔ Outcomes, events, and sample space
✔ Types of events (certain, impossible, and random events)
✔ Probability formula
✔ How to calculate probability step by step
✔ Simple probability questions and solutions
✔ Probability using coins, dice, and cards
✔ Common exam mistakes to avoid

🔹 Probability Formula Explained

Probability is calculated by comparing the number of favorable outcomes to the total number of possible outcomes.

📌 Formula:
Probability of an event = Number of favorable outcomes ÷ Total number of possible outcomes

The value of probability always lies between 0 and 1, where:
• Probability = 0 means the event is impossible
• Probability = 1 means the event is certain

🔹 Worked Examples

This video includes simple and clear examples such as:
• Finding the probability of getting a head when tossing a coin
• Finding the probability of getting an even number when rolling a die
• Calculating probability using simple fractions

These examples help learners understand how to apply the probability formula correctly and confidently in exams.

🔹 Types of Probability Questions

The lesson introduces basic probability questions involving:
• Coins
• Dice
• Playing cards
• Simple real-life situations

These are commonly tested in school examinations and competitive tests.
