Go ahead and take a chance. Given the probability of an event, scholars determine the frequency of the event out of a sample. The part of a review series for the General Certificate of Secondary Education math assessment asks classmates to determine the probability of a complement to an event. The class also determines missing probabilities in a table given a description of the model and other probabilities.
