Counting Methods
1.
What counting method should you use to determine how many different password
combinations are possible: Multiplication Rule, Factorials, Permutations, or
Combinations? Explain.
The method that must be uses for the different password is the permutations. The
permutations give you the most passwords. Because it depends on the order and the order
matters when you are using permutations. Using this method gives you the best numbers and
the most accurate.
2.
If the customer’s cell phone number is 213-745-9806, how many different password
combinations exist? Show all steps in your calculation. N! = 10 = 3628800
3.
Based on your answer to question #2, if you provide the customer with a listing of all
the different password combinations, will it be easy for the customer to determine the
correct password to unlock the phone? Explain by providing the customer with a
recommendation based on your findings. No because there can be over 3628800
different passwords and it would hard for someone to come up with the passwords.
4.
In one paragraph, reflect on the counting methods learned this week by answering the
following: When presented with problems from this module, what strategies did you use
to help you determine which counting method should be applied to solve the problems?
How might you use the different counting methods in your personal/professional life.
The
different types of counting methods I used the ones that was the most relevant to the
problem. It was the best method for the problem.
I looked at what we needed we then used the different methods to figure out what
would fit the methods for the counting methods. Like the problem with the phone number

you want to know what the probability can be for someone getting my password to my
