Ineed on this question me get the answer

Captain umaima has a ship, the h. m.s. khan. the ship is two furlongs from the dread pirate nadia and her merciless band of thieves. the captain has probability 3/7 of hitting the pirate ship. the pirate only has one good eye, so she hits the captain's ship with probability 2/5. if both fire their cannons at the same time, what is the probability that the captain hits the pirate ship, but the pirate misses.

1/4x+5=3/4. i can't get access to the answer to this question! and, my request on "contact us" will not go
