Probability of survival = 80% Good enough...or not nearly good enough? If that is taken as the mean value for the single event, then the probability of surviving 5 dives would have been (0.80)^5 = 0.3277 Kind of slender, 1 chance in 3. With wear and tear, the single event survival probability was probably declining with each dive. "But, who thinks like that?" Answer: people who think for a living.
