What is password?
A password, also known as a passcode, is private information that typically consists of a string of characters and is used to verify a user's identity.
We have to find the number of ways that contain only digits and lower-case letters and having the length is 10.
Since, there are total 10 digits from '0 to 9' and 26 lower case letters from
'a to z'.
The 10 slots in the password can be anything - digits as lower case letters.
that is,
10 + 26 = 36 options for each slot.
So, the total number of ways are, 36^10.
Hence, there are 36^10 ways that contain only digits and lower-case letters and having the length is 10.
