Find the area under the standard normal curve to the right of z = 1.25.

Look in the back of your statistics text for a table labeled something like "areas under the normal distribution." Since you want the values higher than Z = 1.25, use the value in the larger portion.
I hope this helps. 
From the standard normal table find the probability value for Z=1.25, We know that the normal distribution is symmetric and hence area from 0 to 1.25 and area from 1.25 is the same. For the area to the right of 1.25 we add 0.5, which is the right symmetry to the area which we got from the tables and that is your answer.
