The probability P(z ≥ 0.85) in a standardized normal distribution can be found using a Z-table or standard normal distribution table. The value for P(z < 0.85) is approximately 0.8023, so to find P(z ≥ 0.85), you subtract this value from 1 (since the total area under the curve is 1). Therefore, 1 - 0.8023 = 0.1977, which corresponds to option B.
