Title: Clarification of replica set sizes

The line changed was a line I found misleading/a point of concern after being a mongo user for nearly 9 months. Since a two member replica set is an unusual configuration, most users reading the Deploy a Replica Set page are probably better served by indicating that most replica sets are three or more members.
