Concept explainers
A Yellow Lobster! As reported by the Associated Press, a veteran lobsterman recently hauled up a yellow lobster less than a quarter mile south of Prince Point in Harpswell Cove, Maine. Yellow lobsters are considerably rarer than blue lobsters and, according to B. Ballenger’s The Lobster Almanac (Darby, PA: Diane Publishing Company, 1998), roughly 1 in every 30 million lobsters hatched is yellow. Apply the Poisson approximation to the binomial distribution to answer the following questions:
- a. Of 100 million lobsters hatched, what is the
probability that between 3 and 5, inclusive, are yellow? - b. Roughly how many lobsters must be hatched in order to be at least 90% sure that at least one is yellow?
