How many different license plate numbera can be made using 2 letters followed by 4 digits, if letters may be repeated, bht digits are not repeated?

26^2 * 1098*7

Did you know?

Did you know that the number of different license plate numbers that can be made using 2 letters followed by 4 digits, where letters may be repeated but digits are not repeated, can be calculated? To determine this, we need to consider the possibilities for both letters and digits. For the letters, since repetition is allowed, there are 26 choices for each letter. As for the digits, since repetition is not allowed, the first digit has 10 options, the second has only 9 choices (since one digit was already used), and so on. By multiplying the number of choices for letters and digits, we can find that a total of 26 x 26 x 10 x 9 x 8 x 7 different license plate numbers can be made, resulting in a surprisingly large variety of possibilities!
