These are very standard questions regarding normal distribution.  If these are
not homework questions, then you should get yourself a copy of intro stat book.
 Essentially, all you have to do is to convert the question into standard
normal (not Mormal!) distribution, which has zero mean and 1 std.  After that,
you simply look up the probability in standard normal table.
