Binomially distributed
WebYellowdig Discussion Key Information Suppose we look at people living within a low-income census tract in an urban area and we wish to estimate the prevalence of human immunodeficiency virus (HIV) in the community. We assume the number of cases among n people sampled is binomially distributed, with some parameter p. Discussion Prompt … WebApr 8, 2024 · Expert Answer. played until a song by this artist is played. (a) Explain why the probability distribution of x is not binomial. For a random variable to be binomially distributed, the trials must be independent. This is not the case for the random variable x described. For a random variable to be binomially distributed, each trial must always ...

WebBinomial Distribution Overview. The binomial distribution is a two-parameter family of curves. The binomial distribution is used to model the total number of successes in a fixed number of independent trials that have the same probability of success, such as modeling the probability of a given number of heads in ten flips of a fair coin. In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure … See more Probability mass function In general, if the random variable X follows the binomial distribution with parameters n ∈ $${\displaystyle \mathbb {N} }$$ and p ∈ [0,1], we write X ~ B(n, p). The probability of getting exactly k … See more Estimation of parameters When n is known, the parameter p can be estimated using the proportion of successes: See more Methods for random number generation where the marginal distribution is a binomial distribution are well-established. One way to generate See more This distribution was derived by Jacob Bernoulli. He considered the case where p = r/(r + s) where p is the probability of success and r and s are positive integers. Blaise Pascal had earlier considered the case where p = 1/2. See more Expected value and variance If X ~ B(n, p), that is, X is a binomially distributed random variable, n being the total number of experiments and p the probability of each experiment yielding a successful result, then the expected value of X is: See more Sums of binomials If X ~ B(n, p) and Y ~ B(m, p) are independent binomial variables with the same probability p, then X + Y is again a binomial variable; its distribution is Z=X+Y ~ B(n+m, p): See more • Mathematics portal • Logistic regression • Multinomial distribution See more

WebIf x is a binomially distributed random variable with E(x) =2 and van (x) = 4/3 . Find P(x = 5) Solution: The p.m.f. Binomial distribution is. p(x) = n C x p x q n−x. Given that E(x) =2. … WebTo find an estimation of p we need to assume that p is large enough, and to find the estimator we will now assume that p=100. From the question, we know that the change of a winning share is binomially distributed, with n=100 and p=1/42. So first we will look for the expected number of “winning chares” E(winning chares)=n*p=100*(1/42)=2.38

To expand on Victoria's answer, there are a couple more reasons why using a histogram is preferred to visualize the Binomial distribution: 1. The alternative to using a histogram would be to use a line graph.
