Each has a "unique-event" risk of 18%, and the probability of a "super-event" that would disable both at the same time is estimated to be 1.2%.

2) Tommy's Family Furniture is looking for a new supplier for its armchairs. Tommy is primarily interested in only two criterion: price and name brand value. He considers the value of the name brand to be three times more important than price. Tommy has narrowed his choices to two suppliers. On a 10-point scale, he has assigned Amy's Armchairs a score of 8 on price and 5 on name brand value. He has assigned Annie's Armchairs a score of 3 on price and 6 on name brand value.
