WebIf we think of W 1 as the number of trials we have to make to get the ﬁrst success, and then W 2 the number of further trials to the second success, and so on, we can see that X = W 1 + W 2 + ... + W r, and that the W i are independent and geometric random variables. So E[X] = r/p, and Var(X) = r(1−p)/p2. 5 Poisson random variables WebClick here👆to get an answer to your question ️ If p(y) = (y + 2) (y - 2) . Find the value of p(1) .
