Question 468604: assume that a password to log onto a computer account is to consist of any 4 digits or letters (repetition is permitted). Determine the number of passwords possible if the letters are not case sensitive. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Since there are 26 characters in the alphabet, and 10 digits 0 through 9, the total number of characters available in the code is 36. Since they're combined 4 at a time, our answer becomes 36C4, which equals:
36x35x34x33x32!/4x3x2x32!=3x35x17x33=58905 different possible combinations..
