Thanks for the reply anonimnystefy,
Should that be a y instead of an x in the exp(.)?

Any help here would be greatly appreciated! 
Suppose the random variable Y is normally distributed with mean -2 and variance 25.
a) Find the probability that Y exceeds 1, given that Y is positive.
b) Find the expected value of Y, given that Y is positive.
For b) I know its best to first derive the cdf of the RV given by X= (Y|Y>0).
I mainly just need to understand how to do a), However im having trouble.
