Probability — IB Maths AA HL Practice
IB AA HL probability rewards a clear method. Practise reading Venn diagrams, drawing tree diagrams, conditional probability and discrete expectation — each question generates a fresh diagram and re-teaches the exact step you miss.
The idea
What you'll master
- Venn diagram
- Conditional probability
- Without replacement
- Exactly one event
- Discrete distribution
Sample questions
- A survey of 29 people found 15 like tea (T), 18 like coffee (C), and 6 like both. Find the probability a randomly chosen person likes neither.
- Events $A,B$ have $P(B)=0.4$ and $P(A\cap B)=0.1$. Find $P(A\mid B)$.
- A bag holds 4 red and 4 blue balls. Two are drawn without replacement. Find $P(\text{both red})$.
Every attempt generates new numbers — the practice below never runs out.
