The probability is 0.664
If they don't want to be sued, yes. If they don't care.
A z-score gives the distance (specifically number of standard deviations) from the mean so when you compare z-scores, it gives a direct comparison of how far from the mean the values are.
If the z value is that great the probability of the event is ridiculously small (or large) and you'd have to act as if it were near enough zero (or 1)
The main limitation is that the z-transform is appropriate only if the underlying data are normally distributed. It is also important that the estimates for the mean and variance are sufficiently accurate.
