A physical therapist at Enormous State University knows that the football team will play 40 percent of its games on artificial turf this season. He also knows that a football player’s chances of incurring a knee injury are 50 percent higher if he is playing on artificial turf instead of grass. If a player’s probability of knee injury on artificial turf is 0.42, what is the probability that (a) A randomly selected football player incurs a knee injury? (b) A randomly selected football player with a knee injury incurred the injury playing on grass?

Find the probability that a randomly selected person who was unharmed in a fatal crash was not wearing a seat belt.
Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression. What is the probability of a person developing dementia? If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?
A physical therapist at Enormous State University knows that the football team will play 40 percent of its games on artificial turf on this season.
