Two disks are independantly slected. What is the probability that neither contains a missing pulse if the poisson distribution parameter lamda=.2? Solution P(x=0) = e^-2 2^0/0! = e^-2 P(x=0) = e^-2 2^0 / 0! = e^-2 since both are independent !! the probability that neither contains a missing pulse = e^-2 * e^-2 = 0.0183 thus ans.
