With lower case numbers and numerals from 0-9 there are about <u>4,738,381,338,321,616,896 possible passwords.</u>
<u></u>
Add up the number of possible numbers and letters.
There are 26 letters in the alphabet, 0-9 would mean 10 digits. Which is 36.
The length of the password she wants is 12.
36 to the power of 12 = 4738381338321620000
4738381338321620000
if you had the final answer you would divide it by the number of friends
You would have to do 18.18 times 10, keep that answer. then you do 18.18 plus 2.18 and get the answer to that and add it together from the answer from the first question (18.18 times 10)
