Cambridge IGCSE Mathematics practice

MCQ practice - 1 Recognize relative frequency as an approximation of probability, such as using spinner experiment results to estimate the likelihood of a specific outcome. 2 Compute expected frequencies, for instance, applying probability to derive an expected value from a population. This includes grasping the concepts of fairness, bias, and randomness. - Relative and expected frequencies
