You need to have a password with 5 letters followed by 4 even digits between 0 and 9, inclusive. if the characters and digits cannot be used more than once, how many choices do you have for your password?

We all know that there are 26 letters available in the alphabet and there are just 5 even numbers between 0 and 9. We are now given the situation of how many passwords can we make out of the criteria of having 5 letters that cannot be repeated and 4 even digits from 0-9. We cannot repeat the numbers and letters, thus our password will look something like this, , where L is a letter and N is a number. Let us note that  we cannot use the characters and digits more than once.This is how we will solve the probable number of passwords.

26 x 25 x 24 x 23 x 22 x 5 x 4 x 3 x 2

When we compute this formula, we will have the total number of possible passwords:

947,232,000.00

There are 947,232,000 possible passwords based on the given criteria.

Yes that is thw correct answer
