Please provide more information.
1. Did you try quitting the kernel, than re-evaluating these expressions
(after loading the package, of course)? Does this happen every time?
2. Do you get any error messages when loading the package?
3. Are RandomArray[] and NormalDistribution[] defined? Try evaluating
?RandomArray
?NormalDistribution
If you get no error messages and the problem persists after restarting
the kernel then your Mathematica installation is most probably damaged.
