WebThat is, the outcome of any trial does not affect the outcome of the others. If the four conditions are satisfied, then the random variable X =number of successes in n trials, is a binomial random variable with μ = E ( X) = n p (Mean) Var ( X) = n p ( 1 − p) (Variance) SD ( X) = n p ( 1 − p), where p is the probability of the “success." WebThe random variable x is a binomial random variable since the balls are selected with replacement. For this reason, the probability p of choosing a red ball does not change from trial to trial.

WebIan Pulizzotto. The expected value of a difference is the difference of the expected values, and the expected value of a non-random constant is that constant. Note that E (X), i.e. the theoretical mean of X, is a non-random constant. Therefore, if E (X) = µ, we have E (X − µ) = E (X) − E (µ) = µ − µ = 0.
