Kenneth Rosen(7th ed). Chapter 6. Example 16.
Each user on a computer system has a password, which is six to eight characters long, where each character is an uppercase letter or a digit. Each password must contain at least one digit. How many possible passwords are there? Answer is given in book as : P^6 + P ... on for P^7 and P8. My question is why can't we calculate P^6 like 36^5 * C(6,1) * 10 ?

self doubt -kenneth rosen
"In the statement ∃x(x + y = 1), the variable x is bound by the existential quantification ∃x, but the variable y is free because it is not bound by a quantifier and no value is assigned to this variable. This illustrates that in the statement ∃x(x ... y is free becoz it is not bound by a quantifier. thats it!!,Why is no value is assigned to this variable. written?

Kenneth Rosen Edition-7 Chapter-6 Example-8
How many ways are there to distribute hands of 5 cards to each of four players from the standard deck of 52 cards? Why this question can not be solved using the category of COMBINATION WITH REPETITION? I was thinking four players as four boxes with each having 5 balls and 52 cards as 52 similar balls. Please someone clarify the mistake i am doing.
