Best ResponseYou've already chosen the best response.0The out come of the second event here is completely dependent on the first.So for all practical purposes the probability of the second event is 1 provided the first event has happened.so since the probability of the first light bulb lasting a month is .95, the probabilty that the display will last a month is also .95
