WebBinomial Probability Distribution Function (PDF) Given a discrete random variable X that follows a binomial distribution, the probability of r successes within n trials is given by: P ( X = r) = ( n r) p r q n − r. where p is the probability of a success and q = 1 − p is the probability of a failure. WebOct 26, 2024 · I have the following binomial distribution: Last year, the number of new buildings in Community Board 12 and Community Board 11 in the bronx was 347. Of those 347, 107 took place in Community Board 12. If we randomly select 70 of the 347 new buildings, the probability distribution would be: X ~ B (70, 107/ 347)
