WebMar 9, 2024 · Binomial distribution is a common probability distribution that models the probability of obtaining one of two outcomes under a given number of parameters. It … WebThe outcomes of a binomial experiment fit a binomial probability distribution. The random variable X = the number of successes obtained in the n independent trials. The mean, μ, and variance, σ2, for the binomial probability distribution are μ = np and σ2 = npq. The standard deviation, σ, is then σ = \ (\sqrt {npq}\).
WebIn this case, the basketball player attempts 120 free throws with a success probability of 0.75, so we can use the normal distribution to approximate the binomial distribution. a. To find the probability of the basketball player making more than 100 free throws, we can calculate the mean and standard deviation of the normal distribution. WebThe Binomial Distribution If a discrete random variable X has the following probability density function (p.d.f.), it is said to have a binomial distribution: P (X = x) = n C x q (n-x) p x, where q = 1 - p p can be considered as the probability of a …
