Which ratio best defines relative frequency

number of nonfavorable outcomes numbers of possible outcomes

numbers of possible outcomes numbers of nonflavorable outcome

total number of time an experiment is performed numbers of times an events occurs

number of times an event occurs total number an experiment is performed
