
partition problems into sub-problems

identify simpler, related problems

choose and use mathematical methods

Syllabus entries:
3.1.1 simulate everyday chance events with outcomes that are not equally likely
3.2.1 use long-run relative frequency to estimate probabilities
3.3.1 predict the results for repetition of simulations with the same number of trials
3.3.2 use probabilities to predict proportions and number of outcomes that are likely to satisfy provided criteria in n trials
