How many passwords are there which contain 1 One english wor
How many passwords are there which contain:
1. One english word followed by at most 2 digits ( assume there are 2000 possible english words).
2. At most 5 alphabetic characters, digits, or punctuation (or any combination thereof).
Please show your work too, thanks!
edit: it did not specify length
Solution
1. Total possible passwords = passwords with words only + passwords with words and followed by 1 digit + passwords with words and followed by 2 digits
= 2000 + 2000*10 + 2000*10*10
= 222000
2.
Please specify the maximum allowed length of passwords and how many punctuation can be used than only we can calculate the total possible passwords.
