Exam Tips
- Be systematic - use a method to ensure you don't miss outcomes
- Check your count - use the multiplication principle to verify
- Use clear notation - (H,T) for ordered pairs, {H,T} for sets
- Consider order - (1,2) is different from (2,1) in most experiments
- List completely - show all outcomes in the sample space when asked
- Define events clearly - specify which outcomes satisfy the condition
