My Notes (a) For fixed n, are there values of p (0 ≤ p ≤ 1) for which V(X) = 0? (Enter your answers as a comma-separated list. If there is no answer, enter NONE.) p = Explain why this is so. (Select all that apply.) When every trial will be a success, there is no variability in X. When the probability of success is the same as the probability of failure, there is no variability in X. When every trial will be a failure, there is no variability in X. There are no values of p for which V(X) = 0. (b) For what value of p is V(X) maximized? [Hint: Either graph V(X) as a function of p or else take a derivative.] p = Need Help? Read It Talk to a Tutor Submit Answer Save Progress Practice Another Version
