Example 7: An internet company provides TV and Internet services in a certain city, 60% of all houses get Internet service from that company, 80% get TV service from that company, and 50% get both services from that company. a house is randomly selected, 1) what is the probability that it gets at least one of these two services from the company? 2) what is the probability of the event that it get only TV service? 3) what is the probability of the event that a house get only Internet service ? 4) what is the probability of the event that it get exactly one service ? 5) what is the probability that a house get none of each service?
