Question 1077762: Serial numbers for a product are to be made using 2 letters followed by
4 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 9 with no repeats, how many serial numbers can be generated? Answer by math_helper(2461) (Show Source):
You can put this solution on YOUR website! The form of each serial number is XXnnnn
For XX you have 6P2 = (6*5) = 30 possibilities
For nnnn there are 10P4 = (10*9*8*7) = 5040 possibilities
Since the alpha and numeric portions are independent, we need to multiply the above two numbers:
30*5040 = total possible serial numbers
