Suppose that plants of a particular species are randomly dispersed over an area so that the number of plants in a given area follows a Poisson distribution with a mean density of λ plants per unit area. If a plant is randomly selected in this area, find the probability density function of the distance to the nearest neighboring plant. neighbor, then P(R > r ) is the same as the probability of seeing no plants in a circle of radius r.]
