0/1 points | Previous Answers SBioCalc1 7.4.053 My Notes 20. The number of species n found on islands typically increases with the area of the island A. Suppose that this relationship is such that the rate of increase with island area is always proportional to the density of species (that is, number of species per unit area) with a proportionality constant k between and 1. Find the function that describes the species-area relationship. (Let n(1) = n1.) n= X Need...

6. Let the random variables X and Y represent the population of two species/organisms that compete with each other for survival. Suppose that the probability density function p(x, y) of these random variables is proportional to rye-(az+By) (a) What would be an appropriate sample space S for the random variables? Justify your choice of S. (b) Let p(x, y)-Krye-(az-+8v). What should be the proportionality constant K? (c) What is the most probable set of populations (X, Y)? (Hint: The probability...
