GCSE Maths Tutorials — Probability

Probability Basics

Probability basics introduce learners to the concept of chance in GCSE Maths. This subcategory teaches students how to express probability as a fraction, decimal, or percentage, and understand outc...

Probability Scale

Probability scale explores how to represent chance on a continuous scale from 0 to 1. This subcategory teaches students to assign probabilities, compare likelihoods, and interpret values in fractio...

Listing Outcomes

Listing outcomes is a fundamental skill for probability, helping students systematically identify all possible results of an experiment. This subcategory covers generating outcome lists for single ...

Two Way Tables

Two-way tables help students organise and analyse probabilities involving two variables. This subcategory teaches learners to complete tables, calculate joint, marginal, and conditional probabiliti...

Venn Diagrams

Venn diagrams provide a visual method for representing overlapping events in probability. This subcategory teaches students how to organise outcomes, calculate probabilities of unions, intersection...

Mutually Exclusive Events

Mutually exclusive events are events that cannot occur together. This subcategory teaches students how to identify such events, calculate combined probabilities, and apply addition rules. Step-by-s...

Tree Diagrams

Tree diagrams are a systematic way to visualise all possible outcomes in multi-stage probability experiments. This subcategory teaches students how to construct diagrams, calculate probabilities al...

Conditional Probability

Conditional probability examines the likelihood of an event given that another event has occurred. This subcategory teaches students to calculate probabilities using formulas, tables, and diagrams,...

Relative Frequency

Relative frequency introduces learners to probability through experiments and data collection. This subcategory teaches students to calculate probabilities by observing outcomes, recording frequenc...

Theoretical vs Experimental Probability

This subcategory teaches students to compare theoretical probabilities with experimental results, understanding why differences occur. Learners explore patterns, randomness, and the law of large nu...
