Finding probability of z score

WebIf you have the z score of something then you know how many std dev of 1 it is from a mean of 0 with a std dev of 1. If you know the std dev then I think you can just multiply to figure out what the actual value of said z-score then using the std dev you should be able to locate the mean.
