4.5 Mutually Exclusive Probabilities GCSE PowerPoint Lesson

In this 21-slide lesson, students will learn how to calculate the probability of mutually exclusive events occurring. They will explore the definition of mutually exclusive events and use the addition rule: P(A or B) = P(A) + P(B), to find the combined probability of events that cannot happen at the same time. Through worked examples and practice tasks, students will apply this rule to contexts such as dice rolls, spinners, and real-life scenarios. Misconceptions around overlapping events will be addressed to ensure a solid understanding.

The lesson includes:

• Clear, guided examples

• Discussion opportunities from Think, Pair, Share

• Mini whiteboard section to check understanding and clarify misconceptions

• Two structured tasks to practise key skills

• Challenge activity to extend and deepen learning

Perfect for engaging learners while reinforcing essential data and statistics concepts.
