Question 1136995: A factory has seven machines- four of model A and three of model B. At any given moment, there is an 80% chance that a model A machine will be in use. Similarly, model B is used 60 % of the time. If the supervisor walks into the factory at a randomly selected time, what is the probability that two machines of model A and one of model B will be in use? Answer by ikleyn(52810) (Show Source):

will be in use. Similarly, model B is used 60 % of the time. If the supervisor walks into the factory at a randomly selected time,
what is the probability that two machines of model A and one of model B will be in use?
