Binomial distribution problems worksheet. Solution: We ﬁrst realize that P(x= 45 or x= 46) = P(x= 45) +P(x= 46) Now we can use the binomial probability distribution formula to ﬁnd P(x= 45), and P(x= 46) given the fact that q= 1−p= . 2). Given that the mean and the standard deviation of X are both 0. 0. The discrete random variable X has binomial distribution B ,(n p).

What Is Binomial Probability? Binomial probability refers to the possibility of 'x' successes on 'n' numerous trials in an experiment that has two possible outcomes, generally called a binomial experiment.
