(a) Let C denote the time when the room goes dark. Find the pdf of C. b) What is E[C]? Hint: the pdf you obtain in part (a) should be of a familiar type. (c) Suppose light bulb B burns out first. You then move light bulb A to another room, where it is the only bulb. Starting at the time it is turned on in the new room, what is the expected lifetime of bulb A in the new room? Hint: this question can be answered independently of parts (a) and (b).
