In a hotel, suppose 70% of the rooms have showers and 30% have baths. 20% of the rooms with showers are painted blue and 30% of the rooms with baths are painted blue. a) If a room is chosen at random from the hotel, what is the probability that the room is painted blue? b) If a randomly chosen room is blue, what is the probability the room has a shower?
