Answer: There are 35152 different call letters are possible.

Step-by-step explanation:

Given : The call letters for all radio stations in the United States start with either a W (east of the Mississippi River) or a K (west of the Mississippi River) followed by three other letters that can be repeated.

i. e. The total characters = 4

The choices for first letter = 2 (either W or K)

The choices for rest of other letters = 26 (English alphabets has 26 letters)

Then, the number of different call letters are possible = 2 x 26 x 26 x 26

=35152

Therefore, there are 35152 different call letters are possible.
