Answer:

Amy can choose from 60 possible passwords.

Solution:

Given that the two-letter password is from the letters A, B, C, D, E and F

Total number of letters = 6  

The password is a two digit letter and repetition of letters is not allowed.

Method 1:

\therefore The number of ways of obtaining an ordered subset of r elements from a set of n elements is given by

So, the total possible password = = =

On cancelling the in numerator and denominator we get,

Here we get, = 30  possible passwords

Method 2:

There are 6 possible choices for the first term of the password and 5 choices for the second term (i.e. leaving the selected letter of the term)

So,

Answer:

30

Step-by-step explanation:

6 choices for the 1st, then 5 choices for the 2nd, so: 6*5=30

or  nPk=n!/(n-k)!  with n=6 and k=2

Put it simply each letter can be combined with 5 diffrent letters and with 6 total letters 6x5=30

 3/4 is the correct answer

• see ok like you cant get 54 with eight so like 8 x 6=48 k so use one of a distributive property you know of k  so do 8 x 54 is what find you answer and right it down example: hint its a answer to ur question :identity property 432 x 1 is 432 identity property is one of your distributive property simple done boom.!!!!!!!!!!!!!!!!!
