There are 26 choices for the 5 letters in the password (since there are 26 letters in the alphabet) and 5 choices for the first odd digit, 4 choices for the second odd digit, and 3 choices for the third odd digit.
Therefore, the total number of choices for the password is 26 * 5 * 4 * 3 = 1,560 choices.
You need to have a password with 5
letters followed by 3
odd 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?
3 answers
wrong, since there are 5 letters. so the total choices is
26*25*24*23*22*5*4*3
26*25*24*23*22*5*4*3
You are correct. Since there are 5 letters, the total number of choices for the password is:
26 * 25 * 24 * 23 * 22 * 5 * 4 * 3 = 33,638,400
So, there are 33,638,400 choices for the password.
26 * 25 * 24 * 23 * 22 * 5 * 4 * 3 = 33,638,400
So, there are 33,638,400 choices for the password.
