At Burnt Mesa Pueblo, in one of the archaeological excavation sites, the artifact density (number of prehistoric artifacts per 10 liters of sediment) was 1.1. Suppose you are going to dig up and examine 50 liters of sediment at this site. Let r = 0, 1, 2, 3, … be a random variable that represents the number of prehistoric artifacts found in your 50 liters of sediment. a) What is ?? b) Write out the formula for the probability distribution of the random variable r. (Use e, ?, and r in your answer.) P(r) =________ c) Find the probability that you will find three or more prehistoric artifacts in the 50 liters of sediment. (Round your answer to four decimal places.)
