WebLet X be a binomially distributed random variable with mean 2 and variance 4/3. Tabulate the probability distribution of X. For Binomial Distribution, we learnt that the mean (µ) = np, where n is the sample and p is probability of success and the variance σ^2 = np(1 - p). The only thing I could think of doing is: 2 = np and 4/3 = np(1 - p) WebLearn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.

For a binomal random variable, the mean is n times p (np), where n is the sample size and p is the probability of success. The standard deviation is the square root of np (1-p). We can use them to make predictions in a binomial setting. In this example, we look at how many defective chips we expect, on average, in a sample. theory memberdata
