The percentage of marketable oysters that are collected from a large oyster bed varies from day to day. Assume that the random variable that describes this phenomenon follows the beta distribution with ? = 3 and ? = 2 . What is the probability that on any given day the percentage of marketable oysters is between 50% and 70%?

    3. From 2000-2019 there were a total of 3071 earthquakes worldwide with a magnitude of 6 or greater, or an average of about 0.42 such earthquakes per day.* Assume that moving forward the total number of such earthquakes to occur over any time period follows a Poisson distribution with an average of 0.42 earthquakes per day. For the remainder of this question, "earthquake" will mean an earthquake with a magnitude of 6 or greater. Define a new random variable as...
