(1.3x + 2y - 2x + 2 = 3x - 2x + 2y + 2
= (3x – 2x) + 2y + 2
= (3 - 2)x + 2y + 2
= x + 2y + 2

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.
