#563: Fermirotica explain

[A formula is shown with the variables explained above:]

Pd Regional population density (e.g. 18,600/mi²)

Xf Average person’s frequency of sex (e.g. 80/year)

Xd Average duration of sex (e.g. 30 minutes)

r=sqrt(2/(π*Pd*Xf*Xd))

On average, someone within distance r of you is having sex.

Cueball: Mmm, That probable couple 150 meters away is so hot. Oh yeah, theoretically work it, baby.

From out of frame: Hey! No statistical voyeurism!
