Determine the total area under the standard normal curve
(a) to the left of z = -2 or to the right of z = 2
(b) to the left of z = -1.56 or to the right of z = 2.56
(c) to the left of z = -0.24 or to the right of z = 1.20
Find the indicated areas. Be sure to draw a standard normal curve and shade the area that is to be found.
