When using the Poisson distribution, which parameter of the distribution is used in probability computations? What is the symbol used for this parameter?

The Poisson distribution uses the shape parameter denoted by  λ.

Step-by-step explanation:

A Poisson distribution is used to describe the distribution of the number of events that take place in a fixed interval of time.

For instance, number of customers arriving at a bank in an hour or the number of typos encountered in a book every 50 pages.

The Poisson distribution uses the shape parameter to compute the probabilities of different events.

The shape parameter is defined as the average number of occurrence in a given time interval. It is usually denoted by λ.

The probability mass function of a Poisson distribution is:

it is 28 degrees colder in detroit than philadelphia.

what number adds to 21

-7 + ? = 21

-7 + 28 = 21
