In an optics lab we are testing the production quality of an Injection Laser Diode shooting photons (light particles) toward a photosensitive metallic shield. We know that the member of damaged is a random variable X having the probability mass function (1) if r = 1,2,3,... TX (I) = 10 otherwise, where c> 0 is a constant. a) (4 points) Find the value of c b) (4 points) Calculate the probability that the Diode will be able to shoot at least 3 photons.
