Light is absorbed in rods and cones in the retina of the eyes. The number of photons absorbed by aphotoreceptor during a flash is governed by the Poisson distribution. More precisely, the probabilityPn of a photoreceptor to absorb exactly n photons is given by pn = e-^", for d>0(a) Show that Pn = 1.(b) Vision usually occurs when two or more photons are absorbed by the photoreceptor. Calculatethe probability of this occurrence.

Use the following formulae, to obtain the solution. The exponential series can be expressed as…
