Flipping 5 tails in a row has probability (1/2)^5 = 1/32 ≈ 3.13%, making it the most survivable option. Snake eyes (two 1s) on two dice: (1/36)^2 ≈ 0.077%. Rolling a 7 twice: (6/36)^2 ≈ 2.78%. Getting dealt two aces from a standard 52-card deck: (4/52 × 3/51) ≈ 0.45%. The coin flip option has the highest survival probability by a significant margin.
