http://openbooks.library.umass.edu/p132-lab-manual/chapter/the-normal-distribution-and-standard-deviation/ WebYou know Φ(a) and you know that the total area under the standard normal curve is 1 so by mathematical deduction: P(Z > a) is: 1 - Φ(a). P(Z > –a) The probability of P(Z > –a) is P(a), which is Φ(a). To understand this we need to appreciate the symmetry of the standard normal distribution curve. We are trying to find out the area below:

WebFeb 16, 2024 · To find the area to the right of a positive z-score, begin by reading off the area in the standard normal distribution table. Since the total area under the bell curve is 1 (as a decimal value which is equivalent to 100%), we subtract the area from the table from 1. For example, the area to the left of z = 1.09 is given in the table as .8621. WebBelow we see a normal distribution.
