Question

Which of the following correctly describes a Poisson random variable?

a. it does not generate a binomial either/or outcome because only a single type of outcome or "event" is occurring during the Poisson process

b. it is not confined to a fixed number of trials, because its value can equal any discrete integer between zero and infinity, along a continuum of time or space

c. it equals the number of occurrences of a specified event within a specified time or space

d. all of these

e. none of these

Answer 1

Solution :

The correctly describes a Poisson random variable is :

It does not generate a binomial either/or outcome because only a single type of outcome or "event" is occurring during the Poisson process
