Question 266190
How many ways are there of choosing 5 letters, without replacement, from 17 distinct letters, if 
the order of the choices is not taken into consideration?
Ans: 17C5 = [17!/(17-5)!]/5! = 6188
---------------------------
the order of the choices is taken into consideration?
17P5 = 17!/(17-5)! = 17*16*15*14*13 = 742,560
----------------------------------------------
