Ellie wants to change her password which is ellie9 but with same letters and number. in how
many ways she can do that?
p = 256
p = 150
p = 200
p = 179

The number of passwords she can create is an illustration of permutations.

The number of ways to create the password is 179

The password is given as: ELLIE9

The number of characters in the password is:

L and E are repeated twice.

So, we have

The number of new passwords to create is then calculated as:

--- 1 represents the current password
