A football coach knows that his team will play 40% of its games on artificial turf this season. He also knows that a player's chances of incurring a knee injury are 50% 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 randomly selected player incurs a knee injury?
