A trading card series has 200 different cards in it, which are sold in 5-card packages.

Each package has a random sampling of the cards (assume that any card of the 200 has an equal chance of being in a package).

On the average, how many packages will need to be bought to collect the complete series if...

A: all the cards in a package will always be different

B: a package can have repeats

8,000.
200^2 /5
200 cards. Each card has a 1 in 200 chance of being the specific card to fall in line, and there are 5 per package.
