A technology company is going to issue new ID codes to its employees. Each code will have two letters, followed by one digit, followed by one letter.

• The letters D ,Z, G  and Z and the digit 8 will not be used.
• So, there are 23 letters and 9 digits that will be used.

The first letter is chosen from the 23 letters in 23 number of ways. As letters can be repeated, thus second letter chosen from 23 letters in 23 ways.

One digit can be chosen from the 9 digits in 9 different ways. The last letter can also be chosen in 23 ways. Thus, the number of times employee ID codes can be generated is,

$n=23\times23\times9\times23\\n=109503$

Thus, the number of times employee ID codes can be generated is that have two letters, followed by one digit, followed by one letter is 109503.
