This exam tips covers Exam Tips within Sample Spaces for GCSE Mathematics. Revise Sample Spaces in Probability for GCSE Mathematics with 11 exam-style questions and 20 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 5 of 7 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
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
Practice questions for Sample Spaces
A fair coin is flipped and a fair die (numbered 1 to 6) is rolled. How many possible outcomes are there in total?
Explain what a sample space diagram is and why it is useful when finding probabilities for two combined events.
Quick recall flashcards
What is an outcome?
A single result from an experiment
What is a sample space?
The set of all possible outcomes of an experiment
