Question

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. Find the probability distribution of X. Group of answer choices Negative Binomial distribution Geometric distribution None of the given distributions Poisson distribution Binomial distribution Hypergeometric distribution

Answer 1

Poisson distribution.

Explanation:

We have the mean number of missing pulses per disk, which means that the distribution for X, the number of missing pulses, will be the Poisson distribution.

It is not the binomial distribution because we are not given the probability of a missing pulse on a disk, but the mean number of missing pulses.
