Answer:
17,576,000
Explanation:
Assuming we have a license plate with a total of 6 characters (3 letters followed by 3 digits), the number of possible choices for the first position is 26 (the number of letters in the alphabet), while the number of choices for the second and third positions is also 26.
For the last three positions, the number of possible choices for each position is 10 (the numbers from 0 to 9). Therefore, the total number of possible license plates can be calculated as follows:
Total number of possible license plates = 26 x 26 x 26 x 10 x 10 x 10
= 17,576,000
Therefore, there are 17,576,000 different license plates possible with three letters followed by three digits, assuming that digits and letters can be repeated
