WebChapter 5. Distribution calculations. The second module of STAT216 at FVCC focuses on the basics of probability theory. We start out learning the foundations: interpretations of probability (frequentist vs Bayesian) along with the notions of independence, mutually exclusive events, conditional probability, and Bayes’ Theorem. WebOf course, pbinom(0, n, P) always yields the same result as dbinom(0, n, P), irrespective of n or P, and pbinom(n, n, P) should always yield 1.

The arguments for dbinom and pbinom are the same.. The difference is that dbinom looks up the probability of a single outcome P(X = a) ; pbinom looks up the probability of a lower tail area P(X ≤ a) .
