Imagine a soldier in a trench during an armed conflict. In the enemy camp, inside another trench, is an enemy soldier. This soldier can be one of two categories: regular soldiers or snippers. Only 0.1% of enemy soldiers are known to be snippers. The soldier raises his head to out of the trench and a shot hits his helmet. Considering the distance between individuals, a regular soldier would hit that shot 18% of the time while a snipper would hit 87%. Given that the enemy soldier hit the helmet, what is the probability that the enemy soldier is a snipper? (choose only one) a) 0.091 b) 0.0048 c) 0.046 d)0.17 e) 0.13
