The total number of outcomes for this experiment is: A) eight B) four C) six D) two 18. The numerical measure of the likelihood that a specific event will occur is called: A) the sample space B) a sample point C) an event D) the probability of an event 19. The classical probability approach is applied to an experiment that: A) cannot be repeated B) has equally likely outcomes C) does not have more than two outcomes D) has all independent outcomes 20. The conditional probability of event A given that event B has already occurred is written as: A) P(A or B) B) P(B A) C) P(A and B) D) P(A B) 21.
