You can put this solution on YOUR website! A password must contain exactly 8 characters with at least one upper case letter, one lower case letter, one number and one special character. In how many ways can the password be arranged.
=========================
Upper case + lower case = 52 characters
+10 for the numers = 62 chars
Adding 10 "special chars" = 72 (other "special chars" are possible)
------------------
---> 72^8 a big number.
-------------------------------------
= 5184^4
5000^4 = 625,000,000,000,000
