Answer:

0.894

Step-by-step explanation:

This would be the area under the standard normal curve to the right of z = -1.25. There are various ways in which we can calculate this area. I will use a TI-83Plus calculator, which features the necessary normalcdf( function:

normalcdf(-1.25, 1000) = 0.894

So: the area under the standard normal curve to the right of z = -1.25 is 0.894. This area also represents the desired probability.
