SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

In this math video we will be using a tree diagram to determine the number of different combinations possible for desired outcomes. We will learn how to read a tree diagram showing probable outcomes. We will use the tree diagram to...

This video explains how to work with tree diagrams for probability. We explain how to use them to calculate probabilities for a combination of outcomes for more than one event and how to draw a tree diagram for a probability question....

Pupil outcome: I can calculate a conditional probability from a tree diagram. Key learning points: - A tree diagram can be used to calculate conditional probabilities - A tree diagram can be used to calculate conditional probabilities...

Welcome back to Math Defined*! I'm Mrs. C, and today we're diving into **finding probability for a compound event* — where multiple decisions come together to create a whole world of outcomes. ⚽🧦👕



In this lesson,...

Pupil outcome: I can calculate and use theoretical probabilities for combined events using probability trees (2 events). Key learning points: - The probability of an outcome can be found with a probability tree diagram showing all...

Pupil outcome: I can derive the product rule for counting, including when to divide by 2. Key learning points: - By systematically listing the outcomes for two or more events, a pattern begins to emerge - This pattern can be generalised...

The video provides an overview of two mathematical tools used to calculate probabilities: Venn diagrams and probability trees. The speaker explains the concept of sets and elements within a set, and how Venn diagrams can be used to...

Pupil outcome: I can compare and contrast the usefulness of the different representations when calculating theoretical probabilities for combined events. Key learning points: - The probability of an outcome can be found from multiple...

Pupil outcome: I can use formal language for set notation and see how it relates to various representations. Key learning points: - Set notation is a shorter way of writing probability statements - The notation relates to certain aspects...

This video explains the concept of sample space and how to organize all possible outcomes using examples such as gender outcomes and playing Rock, Paper, Scissors. It also introduces the fundamental counting principle and discusses the...

Pupil outcome: I can use my knowledge of advanced algebraic fractions to solve problems. Key learning points: - Real world formula can be complex and contain multiple variables. - When rearranging, you can sometimes check equivalence...

Pupil outcome: I can compare how the requirements of plants can vary from plant to plant. Key learning points: - A good habitat for a plant provides a combination of air, light, water, nutrients from the soil and room to grow. - The...
