A certain ice cream store has 31 flavours of ice cream available. In how many ways can we order a dozen icreams cones if
(a) we do not want the same flavour more than once?
(b) a flavour may be orders as many as 12 times?
(c) a flavour may be ordered no more than 11 times?

31 flavours:
a,b,c,d,e,f,...x,y,z is 26 plus 5 more named: #, $, %, &, and *.
for (a), if you order these 12: yesiwantcold, then is dloctnawisey the same thing?
So like is backwards the same thing, that's what I want to know?

(a) Choosing 12 from 31 , 31!/(12!x(31-12)!) =141120525
(b) 31^12
(c) If each one could be ordered 12 times, then 31^12, If could only be ordered 11 times, then there are 31 situations, which each flavor is ordered 12 times, so its will be 31^12 -31
hope I get it right XD
