PLEASE HELP ASAP!!!!
Captain Ishaan has a ship, the H.M.S. Khan. The ship is two furlongs from the dread pirate Luis and his merciless band of thieves. The Captain has probability 4/5 of hitting the pirate ship. The pirate only has one good eye, so he hits the Captain's ship with probability 1/7. If both fire their cannons at the same time, what is the probability that both the pirate and the Captain hit each other's ships?
