P(a ≤ 2 ≤ b) = (b) - (a). Thus, we can calculate the area of the shaded region, P(0 ≤ Z ≤ 2.74), by finding the area to the left z = b = P(0 ≤ Z ≤ 2.74) = 0 $(0). and subtracting the area to the left of z = a = 0. That is, we can

P(a ≤ x ≤ b) = P(X ≤ b) - P(X < a) = F(b) - F(a) That is, the area between a and b can be calculated by finding the entire area to the left of b and subtracting the area to the left of a. Applying this property for the variable Z with cdf (z), we h P(a ≤ 2 ≤ b) = (b) - (a). Thus, we can calculate the area of the shaded region, P(0 ≤ Z ≤ 2.74), by finding the area to the left z = b = P(0 ≤ Z ≤ 2.74) = ( ) - $(0). , and subtracting the area to the left of z= a = 0.
