Exam Tips
- Always start with the intersection - this is usually given directly
- Work outwards - calculate "only A" and "only B" next
- Find "neither" last - use total minus all other regions
- Check your work - all regions should sum to the total
- Use the addition rule - P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
- Be careful with language - "at least one" means union (∪)
- Label your diagram clearly - show all numbers in their correct regions

Practice Questions for Venn Diagrams
In a Venn diagram with two events A and B, which symbol represents the region where BOTH events occur at the same time?
A student claims: 'To find P(A ∪ B), you simply add P(A) and P(B).' Explain why this is not always correct, and state the correct formula with a reason.
