(APEX-2025) Vehicle license plates serve to give a car a unique identity, allowing tracking and information retrieval by authorities. Consider the Mercosur license plate pattern formed by the sequence of 3 letters, 1 digit, 1 letter, and 2 digits (L1L2L3N1L4N2N3). Considering that all letters of the alphabet and all digits from 0 to 9 can be used, with repetition, indicate how many different combinations we can have for a license plate, knowing that: • The first letter L1 must be A and the fourth letter L4 must be B; • The last two digits N2 and N3 must be 1 and 5, respectively; a) 456,976,000 different combinations b) 411,278,400 different combinations c) 6,760 different combinations d) 1,340 different combinations e) 530 different combinations
