3. Three, Seven, Eight.
When you spell out the words for numbers 1-10 four of the numbers have three letters. (one two six ten)
four, five, nine :)....and zero
Only the number 8 (VIII)
3 This are Three, Seven, and Eight.
This is the answer:OTTFFSSENT are the letters representing the first letter of the numbers 1 through 10.
To calculate the total number of possible combinations for a license plate using 3 letters and 3 numbers, we need to multiply the number of options for each character position. For letters, there are 26 options (A-Z), and for numbers, there are 10 options (0-9). Therefore, the total number of combinations can be calculated as 26 (letters) * 26 (letters) * 26 (letters) * 10 (numbers) * 10 (numbers) * 10 (numbers) = 17,576,000 possible combinations.
There are 26 possible letters and 10 possible numbers. The number of license plates possible is then 26*26*10*10*10*10 = 6760000.

The letters from a to J consist of 10 distinct letters. The number of permutations of these letters is calculated using the factorial of the number of letters, which is 10!. Therefore, the total number of permutations is 10! = 3,628,800.

The answer is 20C10 which is 20!/[10!(20-10)!] = 184756
Because there are only 10 numbers you have to remember. 0123456789. Memorizing a 10 character line of numbers is a whole lot easier than memorizing a 10 character line of letters.
