x is normal with =100 and =15. Find the percentage of people who have IQs of 122 or higher.

(for this question I was confused because in my textbook it says that the area beyond the z score does not include the x value, it is only included between the z score and the mean, that is why I believed we have to use an x value 121 and find the area beyond the z score. However, in the solution it uses the x value of 122; I would appreciate clarification on this.)
