What is the formula for binomial distribution?(a) P [X = x] = ^nCn p^x q^n-x(b) P [X = x] = ^xCx p^x q^n-x(c) P [X = x] = ^nCx p^x q^n-x(d) P [X = x] = ^nCx p^n q^n-xThis question was posed to me in a job interview.The origin of the question is Bernoulli Trials and Binomial Distribution topic in portion Probability of Mathematics – Class 12

Answer»

The CORRECT choice is (C) P [X = x] = ^NCX p^x q^N-x

For explanation I would say: Formula for binomial DISTRIBUTION is P [X = x] = ^nCxp^x q^n-x

Where n is the number of trials, x is the number of successes and (n-x) is failures.
