To estimate the odds of a 79-year-old man living to at least 83 years old, we can use life expectancy data and survival probabilities from actuarial tables or population studies. Based on general demographic data for the United States (e.g., from the Social Security Administration or CDC life tables), we can derive a reasonable estimate.For a 79-year-old man in the U.S., the average life expectancy is approximately 8-9 additional years, meaning they are expected to live to around 87-88 years old. However, this is an average, and we need the probability of surviving at least 4 more years (to age 83).According to the Social Security Administration’s 2020 actuarial life tables (one of the most recent comprehensive datasets), the probability of a 79-year-old man surviving to age 83 can be approximated by looking at annual survival probabilities. On average, for men in this age group, the annual mortality rate is roughly 4-5% per year, meaning the survival probability per year is about 95-96%. Over 4 years, the cumulative survival probability can be estimated as:\[ \text{Survival probability} \approx (0.955)^4 \approx 0.83 \]
This suggests an approximately 83% chance of surviving from age 79 to 83, assuming average health and no specific risk factors. In betting terms, the odds of living to 83 are roughly 83% (or about 5:1 in favor of survival).
