Support · Stage 4 · Probability
Support Explain that observed probability is the relative frequency resulting from repeated trials of a simulation and determine observed probabilities

Assign expected probabilities to outcomes in chance experiments with random generators, including digital simulators, and compare the expected probabilities with the observed probabilities after both small and large numbers of trials

- Interactive toolEnrichmentNRICH: Which Spinners?Use it for: Match spinners to their results using expected vs observed frequency.
Determine and discuss the differences between the expected probabilities and the observed probabilities after both small and large numbers of trials
