2. The quality of computer disks is measured by sending the disks through a certifier which counts the number of missing pulses. A certain brand of computer disks averages 0.1 missing pulse per disk. Let the random variable X denote the number of missing pulses. 2a) What is the distribution of X? Answer: X has a Poisson distribution with mean 0.1. 2b) Find the probability the next inspected disk will have no missing pulse. Answer: P(X=0)=[e^(-0.1)*0.1^0]/0!=0.905 P(X = 0) = 0.905 2c) Find the probability the next disk inspected will have more than one missing pulse
