A password consisting of 2 characters is chosen. The password is randomly chosen by selecting a letter of the alphabet for the first character and a digit (0-9) for the second character. What is the probability the password is L7? I am at a complete loss for how to get started on this, I'm not sure why I can't remember but my mind is totally blank, can someone please explain to me what to do to get myself started on this? Thank you.
