**PsyDAG**, Thursday, December 10, 2009 at 10:31amLook 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.

**Mrs. Lakshmi**, Wednesday, December 30, 2009 at 7:12amFrom 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.
