In a classic ecological paper by Crouse et al., the authors assume that adult loggerhead turtles have (approximately) an 80% chance of surviving from year to year. Let X be the number of years that a loggerhead lives as an adult. (a) What type of random variable is X + 1? (b) What is the probability that a loggerhead lives 5 years as an adult? (c) What is the probability that a loggerhead lives 2 or more years as an adult?
