Let R be a random region in three-dimensional space. In order to calculate the probability that Pinkie Pie is in this region, her normalized wave function is integrated over this region (using the differential volume element (d^3)r ). If this integral is always equal to 1, there is a 100% probability that she will be in an arbitrarily chosen region of space. In other words, she is everywhere at once, at all times.
Equation translation: Pinkies. Pinkies everywhere.
