A survey estimated that 67% of all households with television subscribe to a digital streaming service. Seventy-four percent of all households with television have two or more TV sets. Suppose 55% of all households with television subscribe to a digital streaming service and have two or more TV sets. A household with television is randomly selected.
a. What is the probability that the household subscribes to a streaming service or has two or more TV sets?
b. What is the probability that the household subscribes to a streaming service or has two or more TV sets but not both?
c. What is the probability that the household neither subscribes to a streaming service nor has two or more TV sets?
d. Why does the special law of addition not apply to this problem?
