I'm something of a newbie myself, so I can't completely answer your question
(I can't think of how to make it one function cleanly) but this gets rid of
some of the redundant code:

from random import randrange
from sys import exit
from string import lower

def question():
     n1 = randrange(1, 10)
     n2 = randrange(1, 10)
     answer = int(raw_input('How much is %d times %d? ' % (n1, n2)))
     if answer != n1 * n2:
         return 1
     else:
         return 0

while 1:
     if question():
         print "No. Try again."
     else:
         print "Yes, that is correct."
         again = str(raw_input("Would you like another question (type Y or
N)?"))
         if lower(again) == "y":
             pass
         else:
             exit()

HTH, and I'm sure someone else will chime in with even better ways of doing
it.
