To find the probability of values in a tail of the normal distribution using a standard normal table, we calculate z, find the corresponding probability, and then subtract that probability from 1. This is because the standard normal table provides probabilities for values below the mean (which covers the left tail of the distribution) and we want the probability of values beyond a certain point (which covers the right tail of the distribution). Subtracting the probability we find from 1 gives us the probability of values in the right tail.
