It's going to make a big difference how many characters there are on each license plate.
It's also going to make a big difference how many of them have to be numbers and
how many have to be letters.
-- If each plate has one character, then there are 36 possibilities.
-- If each plate has 2 characters, then there are 1,260 possibilities.
But if it has to be 1 number and 1 letter, then there are only 260 possibilities.
-- If each plate has 3 characters, then there are 42,840 possibilities.
But if it's 2 numbers and 1 letter, then there are only 2,340 possibilities.
And if it's 1 number and 2 letters, then there are 6,500 possibilities.
You can see that in order to answer the question, we need to know more details
about the rules of license-plate formatting.
Any three letters, in any order, including repeated letters gives 263 combinations each of which could have one of 9 digits so 26 x 26 x 26 x 9 ie 158184 different plates.
2600
The number of license plates without a repeated letter or digit is 26x25x24x10x9 = 1 404 000. The number of license plates without any restriction is 26x26x26x10x10 = 1 757 600. Probability of a license plate without a repeated letter or digit = 1 404 000 /1 757 600 = 0.7988 Probability of a license plate with a repeated letter or digit = 1-0.7988 = 0.2022
384,475,000 license plates. There are 35 different letter/number combinations possible. Each combination has 10,985,000 variants. 35*10,985,000 = 384,475,000
26x26x26x10x10x10 = 17,576,000
There are 26 possible letters and 10 possible numbers. The number of license plates possible is then 26*26*10*10*10*10 = 6760000.
If you assume 26 different letters, there are 26 to the power 5 possible variations of 5 letters.
Any three letters, in any order, including repeated letters gives 263 combinations each of which could have one of 9 digits so 26 x 26 x 26 x 9 ie 158184 different plates.
If all letters and numbers are allowed, the possibilities are 26x26x10x10x10x10. So: 6760000 different plates.
11,232,000
Number of possible groups of 3 letters = 26 x 25 x 24 = 15,600. For each of these . . .Number of possible groups of 3 digits = 9 x 9 x 8 = 648 .Total number of possible distinct plates = 15,600 x 648 = 10,108,800
There are 17,576 possible license plates. There are 26 possible letters in the first space times 26 in the second space times 26 in the third space.

The number of license plates without a repeated letter or digit is 26x25x24x10x9 = 1 404 000. The number of license plates without any restriction is 26x26x26x10x10 = 1 757 600. Probability of a license plate without a repeated letter or digit = 1 404 000 /1 757 600 = 0.7988 Probability of a license plate with a repeated letter or digit = 1-0.7988 = 0.2022
384,475,000 license plates. There are 35 different letter/number combinations possible. Each combination has 10,985,000 variants. 35*10,985,000 = 384,475,000
each of the four numbers have 10 possibilities, and each of the three letters have 26 possibilities. so the total possible ways u can arrange them are 10x10x10x10x26x26x26 this totals up to 175,760,000 different license plate numbers
There are 676,000 ways to make the license plates.
