Supernovas are expected about every 100 years

Supernovas are expected about every 100 years. What is the probability that you will be alive for the next one? Use a Poisson model with and estimate your lifetime. (Supernovas actually occurred in 1054 (Crab Nebula), 1572, 1604, and 1987. But the future distribution doesn't depend on the date of the last one.)
