  2. 0.07
  3. 0.6889
  4. 1.20
  5. 83%

Answer(s): A



If the probability that event A occurs is 0.51, the probability that event B occurs is 0.64 and that probability that both A and B occur is 0.23 then:

  1. events A and B are complementary
  2. events A and B are mutually exclusive
  3. events A and B are supplementary
  4. events A and B are not mutually exclusive
  5. events A and B are statistically independent

Answer(s): D



If the probability that event A occurs is .51, the probability that event B occurs is .64 and events A and B are statistically independent then:

  1. A and B are mutually exclusive
  2. the probability that both A and B occur is 0.3264
  3. A and B can’t both occur
  4. the probability that A occurs is 1-(probability that B occurs)
  5. A and B have different standard deviations

Answer(s): B
