Short Answer

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.
What is the distribution of x?
Type of distribution:
