Mathematics for IGCSE & O level - Probability (Section 2 - No. 13)
What is the expected frequency of an event?
probability of an event occurring / total number of trials
probability of an event occurring * total number of observations of an event
total number of trials / probability of an event occurring
total number of trials * probability of an event not occurring
説明
Expected frequency is calculated by multiplying the probability of the event occurring by the total number of observations.
