Explanation / Answer

a) Radio Station Call letters have 3 letters-

K - -

W - -

Total possibilities: 26*26*2

How did I get this?

The next two places can be filled by any of the 26 alphabets

The same is the case with letters starting with W

b) Radio Station Call letters has 4 letters-

K - - -

W - - -

Total possibilities: 26*26*26*2

How did I get this?

The next three places can be filled by any of the 26 alphabets

The same is the case with letters starting with W

So, total possibilities: 26*26*2 + 26*26*26*3 = 54080

This is all assuming that repetition is allowed as nothing is mentioned in the question about it

If that is not the case, do let me know
