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
