A real formula for transition probabilities

Transition probabilities between states in two dimensional quantum systems are derived as functions of unit vectors in R3 instead of state vectors in C2. This can be done once represented states and von Neumann measurements acting on C2 by means of vectors on the unit sphere of R3.
