Question 969457: License plates are made using 2 letters followed by 3 digits. How many plates can be made if repetition of letters and digits is allowed
Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! There are 26 letters, and they may be repeated.
So 26*26=676 are the number of letter possibilities.
Three digits may be 0-9, so there are 10 choices.
10*10*10=1000
There are 676,000 possibilities.
26*26*10*10*10 These are independent, and replacement (repetition) is allowed.
