Probabilities of distinct configurations of the release site with two channels per vesicle. Denoting the open (unblocked) channel probability by po, the probability of both channels being blocked is P(0) = (1 − po)2, whereas the probability of one open channel is P(1) = 2po(1 − po), and the probability of both channels remaining open is P(2) = (po)2.
