Question 1188465
How many different 6-letter radio station names can be made, assuming the first letter must be a K or a W?  Assume repetition of letters is allowed.  Use the Multiplication Principle of Counting to solve the problem
================
The 1st letter is 1 of 2.
Then 1 of 26, 1 of 26 etc
---> 2*26^5
=========================
They're not "station names" they are call signs.
None of them have 6 letters, they have either 3 or 4.
==================
Amateur radio call signs can be 4, 5 or 6 characters, but one of the characters is a number.  
Mine is K8QKQ.  Guy across the street is WB5LVG
