I feel like an idiot for asking but I have never got this concept down. I would appreicate any help on this question.
"Many radio stations in the US have call letters that begin with a W or K and have four letters.
a) How many arrangements of four letters are possible as call letters?
b) What is the probability of having call letters KIDS?
I do want the answer but what I really need is information on holw to solve tis problem.
Thanks out there,
Danny
