Statistics Canada states that 90% of all Canadian households have energy-saving lights. In addition, 40% of all Canadian households have a truck, van, or sport utility vehicle (SUV). Suppose 38% of all Canadian households have both energy-saving lights and a truck/van/SUV. A Canadian household is randomly selected.
a. What is the probability that the household has energy-saving lights or a truck/van/SUV?
b. What is the probability that the household has neither energy- saving lights nor a truck/van/SUV?
c. What is the probability that the household does not have energy- saving lights and does have a truck/van/SUV?
d. What is the probability that the household does have energy- saving lights and does not have a truck/van/SUV?
