A large hotel has five elevators. on any given day, there is an 8% chance that one elevator is broken the elevators operate independently of one another. the robertsons are staying in this hotel for five days. let x represent the number of days one elevator is broken during their stay. what are the mean and standard deviation of x? mu subscript x baseline = 0.4, sigma subscript x baseline = 0.074 mu subscript x baseline = 0.4, sigma subscript x baseline = 0.61 mu subscript x baseline = 2.5, sigma subscript x baseline = 1.92 mu subscript x baseline = 4, sigma subscript x baseline = 0.89
