What are the primary differences between a “normal distribution” and a “standard normal distribution”?

Why would one want to use one over the other?

Solution

The normal distribution can have any mean and standard deviation while standard normal distribution has mean = 0 and standard deviation = 1. To find probability of a normal distribution, one need to transform the normal distribution to standard normal distribution because normal table gives probability for standard normal distribution.
