Option A has the highest survival probability: 5 tails in a row = (1/2)^5 = 1/32 ≈ 3.125%. Snake eyes (two 1s on dice) = 1/36 ≈ 2.78%. Rolling a 7 twice = (6/36)^2 = (1/6)^2 = 1/36 ≈ 2.78%. Getting 2 aces from a 52-card deck = (4/52)×(3/51) = 1/221 ≈ 0.45%. Therefore, flipping 5 tails in a row gives the best chance at ~3%.
