How to find normal distribution probability using mean and standard deviation?

I have values of mean and std deviation as 0 and 0.25 respectively. And I want to get the probability of normal distribution between 1 and -1? I know there is one function makedist which resembles this but it is available in MATLAB 2013a and I have 2012a. So is there any other way?
