Probability (Higher  Unit 1)
Topic:  Probability 
Estimated teaching time:  Higher 5.5 hours  6.5 hours 
Specification references (in recommended teaching order)
S5.1  Understand and use the vocabulary of probability and the probability scale. View assessment guidance > 
S5.2  Understand and use estimates or measures of probability from theoretical models (including equally likely outcomes), or from relative frequency. View assessment guidance > 
S5.3  List all outcomes for single events, and for two successive events, in a systematic way and derive related probabilities. View assessment guidance > 
S5.4  Identify different mutually exclusive outcomes and know that the sum of the probabilities of all these outcomes is 1. View assessment guidance > 
S5.5h  Know when to add or multiply two probabilities: if A and B are mutually exclusive, then the probability of A or B occurring is P(A) + P(B), whereas if A and B are independent events, the probability of A and B occurring is P(A) × P(B) View assessment guidance > 
S5.6h  Use tree diagrams to represent outcomes of compound events, recognising when events are independent. View assessment guidance > 
S5.7  Compare experimental data and theoretical probabilities. View assessment guidance > 
S5.8  Understand that if an experiment is repeated, this may – and usually will – result in different outcomes. View assessment guidance > 
S5.9  Understand that increasing sample size generally leads to better estimates of probability and population characteristics. View assessment guidance >

Please note that, due to the overlap of C/D questions, some material may have been tagged as appropriate for both Foundation and Higher tier. Equally, due to the nature of some questions, different parts of a question may assess different topics. Teachers are advised to ensure learners have covered all of the question content before using such questions.
