Question

In the United States, radio and television stations use four call letters, the first one is either a K or W. How many different call letters with four letters are possible? (For the second, third, and fourth call letter, 26 different letters could be used in each.)

Answer 1

Well, since there are only two possibilities for the first number we can set up the range of possibilities as

2*26*26*26 = 35152 possible combinations.
