Apple products have become a household name in America with 51% of all households owning at least one Apple product (CNN, March 19, 2012). The likelihood of owning an Apple product is 61% for households with kids and 48% for households without kids. Suppose there are 1,200 households in a representative community, of which 820 are with kids and the rest are without kids.
Let event A correspond to "Household with kids", and B to "Household owns an Apple product".
(a) Are the events "household with kids" and "household without kids" mutually exclusive and exhaustive? Explain.
(b) What is the probability that a household is without kids?
(c) What is the probability that a household is with kids and owns an Apple product?
(d) What is the probability that a household is without kids and does not own an Apple product?
