qExample 2: What is the probability that Z lies between the limits Z1=-0.60 and Z2=0.75?
qAnswer:
q    P(Z £-0.60) = 1 - P(Z < 0.60) è P(Z >-0.60)=1-0.7257=0.2743
q    P(-0.60 £Z £0.75) = P(Z £0.75) - P(Z £-0.60)
q                                  = 0.7734 - 0.2743
q                                  = 0.4991
