Question 1105063: Serial numbers for a product are to be made using 4 letters followed by 3 numbers. If the letters are to be taken from the first 6 letters of the alphabet with no repeats and the numbers are taken from the digits 0 through with no repeats, how many serial numbers can be generated? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 6*5*4*3*10*9*8, since no repeats are allowed. It is essentially a tree diagram.
360*720=259200.
