A catalyst researcher states that the diameters, in microns, of the pores in a new product she has made have the exponential distribution with parameter λ = 0.25. Suppose that the diameters of 10 pores are independent. a) Find the probability that more than seven of them have diameters less than 3 microns. b) Find the probability that exactly one of them has a diameter greater than 11 microns.
