Probability Explained | Rules, Tree Diagrams, Sample space & Worked Examples by Mr. Stephen

Описание: In this video, you will learn Probability beyond the basics, explained in a clear and exam-friendly way. This lesson is suitable for secondary school, high school, and senior mathematics students who already understand simple probability and want to improve their problem-solving skills.

Probability is an important topic in mathematics that helps us understand chance, uncertainty, and outcomes. It is widely used in statistics, science, economics, finance, games, and real-life decision making. In this lesson, we focus on probability rules and multi-step questions that commonly appear in examinations.

🔹 What You Will Learn in This Video

✔ Review of basic probability concepts
✔ Probability rules and laws
✔ Independent events
✔ Combined events and outcomes
✔ Tree diagrams for probability
✔ Step-by-step worked examples
✔ Exam-style probability questions
✔ Common mistakes students make

🔹 Probability Rules Explained

This video explains important probability rules used to solve more challenging questions, including:
• Probability of combined events
• Probability of independent events
• Using fractions and tables in probability
• Organizing outcomes correctly

You will learn how to apply these rules accurately when dealing with two or more events, such as tossing coins multiple times or rolling dice.

🔹 Tree Diagrams in Probability

Tree diagrams are an effective way to represent probability experiments involving more than one stage. In this lesson, you will learn how to:
• Draw a probability tree diagram
• Label probabilities correctly
• Multiply probabilities along branches
• Find final probabilities from the diagram

Tree diagrams make probability questions easier to understand and solve, especially in exams.

🔹 Worked Examples

This video includes worked examples involving:
• Tossing coins more than once
• Rolling dice
• Finding probabilities of combined outcomes
• Using tree diagrams to calculate probabilities

Each example is explained step by step to help learners gain confidence and accuracy.

🔹 Who Should Watch This Video?

• Secondary and high school mathematics students
• Learners preparing for exams
• Teachers and tutors
• Anyone improving probability problem-solving skills
