"WebbFor example, f ( 0.9) = 3 ( 0.9) 2 = 2.43, which is clearly not a probability! In the continuous case, f ( x) is instead the height of the curve at X = x, so that the total area under the curve is 1. In the continuous case, it is areas under the curve that define the probabilities. " - Probability solved examples

Then we will subtract the smaller value from the larger value: 0.8413 – 0.6554 = 0.1859. Thus, the probability that a value in a given distribution has a z-score between z = 0.4 and z = 1 is approximately 0.1859.
