Neither (a) nor (b).  It is c) you have named your program "math.py" but
"math" happens also to be the name of a module in the standard Python
library, and the "random" module needs access to the "math" module.  But
when it searches the Python path for a module named "math" it comes upon
your file first.

Simple solution:  call your program something else!  (and make sure you
delete math.py? from your working directory).
