WebSep 12, 2024 · You get 1E99 (= 10 99) by pressing 1, the EE key (a 2nd key) and then 99. Or, you can enter 10^99instead. The number 10 99 is way out in the right tail of the normal curve. We are calculating the area between 65 and 10 99. In some instances, the lower number of the area might be –1E99 (= –10 99). 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.
