5.5.4 Consider spheres in three-dimensional space with centers distributed according to a Poisson distribution with parameter jAj, where jAj now represents the volume of the set A. If the radii of all spheres are distributed according to F.r/
with density f .r/ and finite third moment, show that the number of spheres that cover a point t is a Poisson random variable with parameter 43
R1 0 r3f .r/dr.
