Here’s a fun fact: “poisson” means “fish” in French, so here’s a fishy problem to help youremember the Poisson distribution!Suppose you’re fishing at Lake Bryan, and at your fishing spot, you figure that on average,4 fish swim within range of your fishing lure every 30 minutes.(a) What is the PMF for X = number of fish that swim within range of yourfishing lure in the next 30 minutes?(b) What is the probability that no fish come within range of your fishing lurein the next 30 minutes?(c) What is the probability that at least 6 fish come within range of your fishinglure in the next 30 minutes?
