<PRE><B>Question 365866</B>
 How do you solve: 
Radio stations in the United States have call letters that begin with K or W (for west or east of the Mississippi River, respectively). Some have three call letters, such as WBZ in Boston, WLS in Chicago, and KGO in San Francisco. Assuming no repetition of letters, how many three-letter sets of call letters are possible?
1st letter: 2 ways
2nd letter: 25 ways
3rd letter: 24 ways
----
Total # of 3-letter sets = 2*25*24 = 1200
