Suppose you talk to a lot of registered republicans and democrats, but haven"t found an independent yet. Let x be a r. v. describing the number of people you have interviewed up to including your first registered independent voter. Suppose you"re really interested in talking to a lot of independents. let x be a r. v. describing the number of people you have interviewed up to to talk to in order to interview exactly 100 registered independents.
