WebbThe 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.

WebbThe pbinom function normally assumes that you want the lower tail of the distribution, that is the probability of getting less than or equal to a specified value. The specification "lower.tail=FALSE" tells R to compute the upper tail of the distribution, that is the probability of getting a value greater than the argument.
