Question 310543: You are trying to collect all nine baseball cards for an All-Star team. Each package of cards he can buy has one card of a member of the team. The cards are equally distributed among all the packages. How could you use a simulation to estimate the number of packages of cards you will need to buy to get all nine cards?

You can put this solution on YOUR website! You are trying to collect all nine baseball cards for an All-Star team. Each package of cards he can buy has one card of a member of the team. The cards are equally distributed among all the packages. How could you use a simulation to estimate the number of packages of cards you will need to buy to get all nine cards?
------
Let the digits 1 thru 9 represent the card different baseball cards.
----
Pick an arbitrary starting point on a random-number table.
Count how many digits you have to read thru till you have seen
a 1, a 2, a 3, a 4 ...,an 8, and a 9.
-----------------
Pick another random starting point or continue from where you
left off after the 1st count.
Again, count how many digits you have to read thru till you have
seen the digits 1 thru 9.
Do that 25 times; find the average number of the counts.
That is the estimated number of packages of cards you would
have to buy to get the 9 cards you are looking for.
