WebNotes. The probability mass function for bernoulli is: f ( k) = { 1 − p if k = 0 p if k = 1. for k in { 0, 1 }, 0 ≤ p ≤ 1. bernoulli takes p as shape parameter, where p is the probability of a single success and 1 − p is the probability of a single failure. The probability mass function above is defined in the “standardized” form.
