Air Bag Safety According to a study conducted by the a public health school, a child seated in the front seat who was not wearing a seatbelt was 85% more likely to be killed in an accident if the car had an air bag that deployed than if it did not. Airbags deployed in 25% of all accidents. For a child seated in the front seat not wearing a seatbelt, what is the probability that the airbag deployed in an accident in which the child was killed? (Round your answer to two decimal places.) HINT [When we say "A is 85% more likely than B" we mean that the probability of A if 1.85 times the probability of B.]
