Definition The Binomial Random Variable Definition A random variable X whose probability mass function is given by f x P X x begin cases binom n x p x If X B n p and Y X B X q the conditional distribution of Y given X then Y is a simple binomial random variable with distribution Y B n pq For example imagine throwing n balls to a basket U X and taking the balls that hit and
Then X is a binomial random variable with parameters n 5 and p 1 3 0 bar 3 Note that the probability in question is not P 1 but rather P X leq 1 Using the cumulative The random variable X the number of successes obtained in the n independent trials The mean and variance 2 for the binomial probability distribution are np and 2 npq

What Is a Binomial Random Variable A binomial random variable is a number of successes in an experiment consisting of N trails Some of the examples are The number of successes tails in an experiment of 100 trials Suppose X is binomial B n p How can I find the probability that X is even I know P X k frac n n k k p k 1 p n k where X 1 n Are they just
If I know X is a binomial random variable how can I find the distribution of X squared I know that P Y y x 2 p X x but does this distribution have a standard name In Use our binomial probability calculator to get the mean variance and standard deviation of binomial distribution based on the number of events you provided and the
