IB Maths AI SL 4.7 – Discrete Random Variables & Expected Value Notes

IB Maths AI SL 4.7 Notes – Discrete Random Variables & Expected Value

This IB Maths AI SL 4.7 resource covers Discrete Random Variables and Expected Value and is fully aligned with the IB Applications and Interpretation syllabus

Students learn how to work with discrete probability distributions, apply the condition ( \sum p(x) = 1 ), determine missing constants, calculate probabilities such as ( P(X \geq 2) ), and compute expected value using ( E(X) = \sum x p(x) ). The idea of a fair game is also explored through expected profit.

The file includes a teacher copy with fully worked solutions and clear explanations, making it ideal for efficient instruction and exam preparation.

Perfect for IB Maths AI SL teachers teaching Topic 4 probability and expected value.
