Find the area under the standard normal distribution curve to the left of z=-2.15 and to the right of z=1.62

The area under the standard normal distribution represents probability from 0 to 1.
So, what's being asked, in essence, is what is P(Z ≤ -2.15) and P(Z ≥ 1.62).
P(Z ≤ -2.15) = 1 - P(Z ≤ 2.15) = 1 - 0.9842 = 0.0158.
P(Z ≥ 1.62) = 1 - P(Z ≤ 1.62) = 1 - 0.9474 = 0.0526
