This IB Math AI SL 4.7 – Discrete Random Variables & Expected Value resource builds students’ understanding of how numerical outcomes from random processes are modelled and analysed. Students learn to distinguish discrete from continuous variables, work with probability mass functions (pmfs), verify valid distributions, and calculate expected value as the long-run average outcome. Applications to games of chance and fair pricing help connect theory to decision-making contexts.

Structured tasks progress from vocabulary and classification to using functions to define pmfs, finding unknown constants, computing expected value from tables, and analysing expected gains in real-life game and insurance scenarios. Extended problems develop deeper reasoning with algebraic expected value expressions, fairness conditions, and multi-step probability models. With scaffolded practice, exam-style questions, and a full answer key, this resource supports SL classroom teaching and independent study in line with IB Mathematics AI expectations.

IB Math AI Unit 4 Worksheet Bundle - All Sections Included!

This **IB Mathematics AI Unit 4 – Statistics Bundle** provides a complete set of structured worksheets covering the full statistics strand of the IB Math Applications & Interpretation course. The materials guide students from foundational statistical concepts through interpretation, analysis, and critical evaluation of data, building both procedural fluency and conceptual understanding required for IB assessments. Across the bundle, students work with data collection methods, sampling techniques, measures of central tendency and spread, representation of data, correlation and regression, probability distributions, and hypothesis testing. Tasks are sequenced to move from skill-building exercises to exam-style and extended-response problems, helping learners connect statistical calculations to interpretation in real-world contexts. Emphasis is placed on understanding assumptions, identifying bias and limitations, and interpreting results in context, all key expectations of the AI course. Each worksheet follows a consistent layout and structure to support classroom use, homework, revision, and independent study. Clear scaffolding, varied question styles, and challenge problems develop higher-order reasoning alongside core techniques. A full answer key is included for every worksheet, making this bundle ideal for teachers delivering the Unit 4 statistics syllabus or students preparing for internal and external IB assessments.
