If you knew for certain that you were going to die, but hopping on one foot would give you a 60% chance to live, would you do it? Now what if rubbing your belly gave you a 30% chance to live, and patting your head gave you 10% chance? But if you do all 3 you have a 100% chance to live. Would you only hop on one foot since that’s the most effective? No, you would do all 3, combining the methods for maximum effectiveness. Your argument is no different, except you’re saying in this non-hypothetical situation you’re only going to do one thing.
