A company decides to give ID numbers to its employees that consist of one letter followed by three digits. How many different such ID numbers are there?

25,974 possible ID combinations

Step-by-step explanation:

Since the ID card will consist of one letter and three digits to find the total number of possibilities we simply multiply the number of letter options that exist by the total amount of numbers each letter can be followed by. There are a total of 26 letters in the English Alphabet. Since each letter is followed by only 3 digits, then the largest number that can exist after the letter is 999. Therefore, we simply multiply 26 by 999 to find the total number of possible outcomes.

26 * 999 = 25,974 possible ID combinations
