Answer:
10 without repetitions, or 35 with repetitions
Step-by-step explanation:
Okay so basically if you allow repetitions, which would be repeating the same letter more than once, such as AAB, or BBD, or DDD, then there would be 35 total combinations. IF you do not allot repetitions and it has to be answers such as ABC, DEA, CAE, DCB, there would be only 10 possible passwords. Hope this helps. Brainiest is much appreciated
