To state: The numbers of different entry codes that can be created if you need to first choose a letter and then, three single-digit numbers.
The resultant codes are 26,000.
Given information:
Every code begins with a letter and then three single-digit numbers.
Explanation:
Consider the given information,
The code begins with a letter and then three single-digit numbers.
There are 26 letters in alphabets and there are 10 digits from 0 to 9. For forming a code these 26 letters and 10 digits are to be used.
The first two letter of the code can be selected in 26 ways.
The next three places are to be filled with three single numbered digits. The number of ways for it is:
Now the total number of ways will become:
Therefore, 26,000 codes can be created.
