Question 1
Situation: Factory fire with 50 workers inside. You can either: try to extinguish fire (30% success, 10 minutes, saves all) or evacuate (100% success, 5 minutes, saves 40 workers).
What is the best decision in this emergency situation?
Expected value: Extinguish = 50×0.3 = 15 expected saved; Evacuate = 40 guaranteed saved. Guarantee of 40 saved is better than 15 expected.
