find optimal way to seprate these classes

I have two class first one is mean=0 and standard deviation=0.5 ,for the second class my mean is 1 and standard deviation=5.how can I seprate them in the best way. is there any algorithm for this problem?

It’s not clear what is being asked here - what are you trying to separate? You have data for two classes, one with a mean of 0 and a standard deviation of 1? As the question is posed, you have 4 numbers, so it’s not clear what the problem is.
