Suppose P(Z > z*) = 0.80. Select the two reasons why P(Z > z*) = 0.20. Because these two events are complements and the sum of their probabilities must be one. Because z* is so small. Because the total area under the probability density curve equals 1. Because P(Z > z*) - P(Z > z*) always equals 0.60.
