Question 1031969
If there are 10 toys available for purchase and they are all different. How many distinguishable ways are there for Diane to buy 3 toys if she is sending them to 3 nephews living in 3 different households. 
-------------------
Select 3 toys from 10:: 10C3 = (10*9*8)/(1*2*3) = 120 ways
---------------------
Send to 3 households:: 3*2*1 = 6 ways
