1. In a game of Galactic Unicorns your Monocerian-class space frigate is attacking an evil Sargonian robot ship.  Your attack will either hit or miss the robot ship, the probability of hitting the ship is 0.7.  If you hit the robot ship then there is a probability of 0.8 that the ship will be destroyed, otherwise it will manage to escape.  If you miss the robot ship then there is a probability of 0.2 that it will manage to escape, otherwise it will surrender because it has witnessed the immense power of your rainbow lasers.
