Problem 36
Question
How many different four-letter radio station call letters can be formed if the first letter must be W or K?
Step-by-Step Solution
Verified Answer
There can be 35152 different four-letter radio station call letters formed where the first letter must be either W or K.
1Step 1: Identifying letters choice
There are 2 choices for the first letter (W, K) and 26 choices each for the second, third, and fourth letter.
2Step 2: Calculating combinations
Since each choice is independent, we multiply the number of choices together: \(2 * 26 * 26 * 26 = 35152\).
