In one of the archacological excavation sites, the artifact density (number of prehistoric artifacts per 10 liters of sediment) was 2.5. Suppose you are going to dig up and examine 40 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 40 liters of sediment. Write the formula for the probability distribution of the random variable r. a. P(r)=r!e−100000rr​ b. P(r)=(r+1)!e−160(160)r+1​ C. P(r)=r!e−160(16.0)r​ d. P(r)=(r+1)!e−1.0(1.0)r+1​ e. P(r)=r!e−11.0(11.0)r​
