To survive, you must succeed at the probability task. Compare probabilities: 5 tails = (1/2)^5 = 1/32 ≈ 3.1%, Snake eyes = (1/6)(1/6) = 1/36 ≈ 2.8%, Two 7s = (1/6)(1/6) = 1/36 ≈ 2.8%, Two aces = (4/52)*(3/51) ≈ 0.45%. 3.1% is the highest survival probability. The 'punishments' are irrelevant - you either succeed at the task (live) or fail (die).
