A song that may be used in discussing the concept of independence as P(A) = P(A|B). The lyrics were written by Mary McLellan from Aledo High School in Aledo, Texas as one of several dozen songs created for her AP statistics course. The song may be sung to the tune of the folk Ballad Oh My Darlin’, Clementine assumed to have been written by Percy Montrose in 1884.
