consider two events a and b. if the probability of a given b is 0.3, then: (pick one) a. the probability of a given the complement of b is 0.7. b. the probability of the complement of a given the complement of b is 0.7. c. the probability of the complement of a given b is 0.7. d. events a and b are mutually exclusive if the probability of a is 0.3. e. none of the above.
