#1. There are 26 possibilities for the first letter, 26 for the second letter and 10 for the last part ( assuming 0 is used). Assuming that the use of a letter in the first position doesn’t affect using it in the second position ( can use the same letter twice), these three things are independent of each other and thus the number of possible permutations is given by multiplying all three numbers ( 26 x 26 x 10). But it’s been awhile since I’ve done my stat course.
2. See #1. Actually, this can surely help you understand the idea of independent event.
