members of a video club choose a PIN consisting of two letters and two digits.
How many PINs are possible if neither letter nor digits may be repeated?
------------------------By using the basic counting principle
The PINS have 4 spaces: _ _ _ _
The first space: 26 choices (letters)
The second space: 25 choices (letters) since no letter is repeated.
The third space: 10 choices (10 numbers)
The final space: 9 choices (9 letters) since no number is repeated.
So the total PINS is 26 * 25 * 10 * 9 = 58,500
Hope it helps you :)
