- Assume that the probability that an airplane engine will fail during a torture test is 12and that the aircraft in question has 4 engines. Construct a sample space for the torture test. Use S for survive and F for fail.arrow_forwardIf a binomial experiment has probability p success, then the probability of failure is ____________________. The probability of getting exactly r successes in n trials of this experiment is C(_________, _________)p (1p)arrow_forwardThe CDF F(x) of a random variable X is given by; F(x) = { 0, ?? ? ≤ 1 ?(? − 1)^4 , ?? 1 < ? ≤ 3 1, ?? ? > 3 } i) the mean and variance of X.arrow_forward

Assuming that each cake can be sold only on the day it is made, how many chocolate cakes should he bake to maximize his expected profit? || || ||arrow_forwardLet f(x, y) = x + y for 0 < x < 1 and 0 < y < 1 The Conditional Variance of Y when X = ; isarrow_forward
