Based on your coin flips, you have chosen building to rob. Although it has no electric fences and no closed circuit cameras, the money is guarded by a gigantic hound. Fortunately, you have gem powered gun, which is capable of putting any person or animal to sleep instantly. Unfortunately, that power only works half the time ( that is, each time the weapon is fired, the probability of making the target fall asleep is 1/2 ).
