Unordered selections

Abstract

In this lesson, we continue “selections from an urn” but without distinguishing the order of selection. The classical example is again from gambling—in many card games, the order in which the dealer passes you the cards does not effect the value of the hand. Here we have sampling without replacement as well as without regard to order. In collecting baseball pictures (in packs of chewing gum in the old days), matchbooks, stuffed dolls, etc., usually order is not important but one takes account of repetitions—replications.
