Example 2

The variable Z is a standard normal random variable. What is the probability that z is greater than 1.2 or less than -1.2?

Figure 18

The desired area is to the right of 1.2 and to the left of -1.2. Since normal distributions are symmetrical, and the areas are the same, you can calculate the lower tail area and simply multiply by 2.
