There are 7,800 different passwords.

<h3>How many different passwords can be generated?</h3>

Here we need to count the number of options for each of the digits of the password.

The first character has 26 options (26 letters in the alphabet).

The second character has 10 options (ditis from 0 to 9), and also does the third character

The fourth character has 3 options (%,*, or #)

The total number of different passwords that can be generated is given by the product between the numbers of options, so we have:

C = 26*10*10*3 = 7,800

There are 7,800 different passwords.
