# Probability topics for intermediate level

Below are the intermediate topics available for the category "Probability" at Free Maths Games.

These free maths topics offer a complete set of basic Probability topics for intermediate pupils aged 11 to 14. The Probability category is divided into sub-categories such as "Expressing probability", "Venn and tree diagrams", etc. Each sub-category has multiple sub-sub-categories, and within them are the topics with between 6 and 10 question and answer pairs for the lessons, plus additional question answer pairs for the games and tests.

For each question/answer pair in a topic you get the question as picture, equation or text, the spoken question read by a robot, and an answer as both number or text and as audio. For most topics there are also 3 wrong answers prepared for each question.
