Unformatted text preview: p and undetected with probability (1p ) independent of N and other photons. Let X be the number of detected photons per unit time. Thus X = ∑ N i =1 Z i , where Z i = b 1 , photon i is detected , photon i is not detected and for each N = n, { Z 1 ,Z 2 ,... ,Z n } are independent. Find the mean and variance of X . Problem 7 is an optional question, those who solve it will get extra credits. 7. Solve 3.40 (3.40) from textbook. Do part (c) for only part (a) (not for part (b)). Note : 3.2 (3.1) implies problem 3.2 from the ninth edition which is the same as 3.1 in the eighth edition....
