Let XXX be a random variable representing the number of components failing before 100 hours, following a Binomial distribution B(n=10,p=0.2)B(n=10, p=0.2)B(n=10,p=0.2). If each failure costs \50inrepairs,whatisthevarianceofthetotalrepaircostin repairs, what is the variance of the total repair costinrepairs,whatisthevarianceofthetotalrepaircostY = 50X$?
