Summary: The paper deals with a generalisation of the so called collector’s problem, a known problem from probability theories, when we are interested either in: { indent=6mm\item{-} how many cards we should buy in order that an event with a given probability happens or \item{-} how many cards we have to buy on average to make a collection complete. } The generalisation is based on a more realistic background when we do not buy cards separately but in sets of several pieces.
