Mathematics for IGCSE & O level - Probability (Section 8 - No. 31)
How do you calculate the expected frequency of an event?
Total number of outcomes / the probability of the event occurring.
Total trials * The probability of the event not occurring.
Probability of the event occurring / Total trials
Probability of the event occurring * total number of observations of the event.
توضيح
The expected frequency is calculated by multiplying the event's probability by the number of observations.
