Here's the question:
Assuming that the z-scores are normally distributed, the mean equals 0, and the standard deviation equals 1, and P(z>c), find "c".

thanks!!

You have not given a value for the probability. When you have one, the solution is in the normal distribution table.

what if the teacher didn't give a table? : [
or a value for the probability

Then you should use whatever technology (Excel, your graphing calculator, etc) that was provided.

or a value for the probability

Then this necessary information is missing, and you will need to obtain it from your instructor.
