Question

If a license plate number starts with a letter of the alphabet followed by 5 numeric digits, how many license plate numbers can be constructed if the first numeric digit cannot be a zero?

Answer 1

There are 26 ways to choose the letter.
There are 9 ways to choose the first digit, since 0 is not allowed.
here are 10 ways to choose each other digit.

SO, the total ways to choose the plate number is 26*9*10000 = 2340000
