The punctuality of trains has been investigated by considering a number of train journeys. In the sample, 60% of trains had a destination of Manchester, 20% Birmingham and 20% Edinburgh. The probabilities of a train arriving late in Manchester, Edinburgh or Birmingham are 30%, 20% and 25% respectively. If a late train is picked at random from the group under consideration, what is the probability that it terminated in Manchester?

According to a study conducted by a public health school, a child seated in the front seat who was wearing a seatbelt was 32% 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 28% of all accidents. For a child seated in the front seat 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 32% more likely than B" we mean that the probability of A if 1.32 times the probability of B.]
