11,232,000 different plates

Step-by-step explanation:

Figure it out like this:

2letters * 3digits * 1letter

Nothing can repeat. There are 26 letters in the alphabet. If we use 1 of those letters, then there are only 25 letters left to choose from. That's why we start with 26 * 25.

Now for the digits, we have 10 choices for the first digit, then 9 choices for the second digit, then 8 choices for the third digit. That's why we follow the letters with 10 * 9 * 8.

For the last letter, we had 24 choices left, so the whole thing is found by multiplying:

26 * 25 * 24 * 10 * 9 * 8 * 24 = 11,232,000
