Sorry, I'm gay. I don't like Poussin.

Well there is a non-sequitur if there ever was one🤡.

Fish. (Poisson, I know, but clearly someone went to college.)

It's about death, not hardons. Death is the ego.

Poisson Distribution Table

As with the binomial distribution, there is a table that we can use under certain conditions that will make calculating probabilities a little easier when using the Poisson Distribution. The table is showing the values of f(x) = P(X ≥ x), where X has a Poisson distribution with parameter λ. Refer the values from the table and substitute it in the Poisson distribution formula to get the probability value. The table displays the values of the Poisson distribution.

Poisson Distribution Mean and Variance

Assume that, we conduct a Poisson experiment, in which the average number of successes within a given range is taken as λ. In Poisson distribution, the mean of the distribution is represented by λ and e is constant, which is approximately equal to 2.71828. Then, the Poisson probability is:

P(x, λ ) =(e^{– λ} λ^x)/x!

In Poisson distribution, the mean is represented as E(X) = λ.

For a Poisson Distribution, the mean and the variance are equal. It means that E(X) = V(X)

Where,

V(X) is the variance.

Poisson Distribution Expected Value

A random variable is said to have a Poisson distribution with the parameter λ, where “λ” is considered as an expected value of the Poisson distribution.

The expected value of the Poisson distribution is given as follows:

E(x) = μ = d(e^λ(t-1))/dt, at t=1.

E(x) = λ

Therefore, the expected value (mean) and the variance of the Poisson distribution is equal to λ.

Poisson Distribution Examples

An example to find the probability using the Poisson distribution is given below:

Example 1:

A random variable X has a Poisson distribution with parameter λ such that P (X = 1) = (0.2) P (X = 2). Find P (X = 0).

Solution:

For the Poisson distribution, the probability function is defined as:

P (X =x) = (e^{– λ} λ^x)/x!, where λ is a parameter.

Given that, P (x = 1) = (0.2) P (X = 2)

(e^{– λ} λ¹)/1! = (0.2)(e^{– λ} λ²)/2!

⇒λ = λ²/ 10

⇒λ = 10

Now, substitute λ = 10, in the formula, we get:

P (X =0 ) = (e^{– λ} λ⁰)/0!

P (X =0) = e^-10 = 0.0000454

Thus, P (X= 0) = 0.0000454

Example 2:

Telephone calls arrive at an exchange according to the Poisson process at a rate λ= 2/min. Calculate the probability that exactly two calls will be received during each of the first 5 minutes of the hour.

Solution:

Assume that “N” be the number of calls received during a 1 minute period.

Therefore,

P(N= 2) = (e^-2. 2²)/2!

P(N=2) = 2e^-2.

Now, “M” be the number of minutes among 5 minutes considered, during which exactly 2 calls will be received. Thus “M” follows a binomial distribution with parameters n=5 and p= 2e^-2.

P(M=5) = 32 x e^-10

P(M =5) = 0.00145, where “e” is a constant, which is approximately equal to 2.718.

Your response and understanding  of the theme and its postings is sadly myopic.

The literal translation of "Et in Arcadia Ego" is "Even in Arcadia, there am I". Poussin's earliest biographer, Giovan Pietro Bellori, understood the 'I' of the phrase to refer to Death, thus making the painting a memento mori, reminding the viewer that even in the blissful utopia of Arcadia, death still exists.^[3] Another biographer, André Félibien, interpreted the 'I' to refer to the occupant of the tomb, but still took the overall meaning of the painting to be a reminder that death is present even in idyllic Arcadia.^[4]

The vagueness of the phrase is the subject of a famous essay by the art historian Erwin Panofsky, who suggested that, compared to Poussin's 1627 version, this second version shifted the focus from a warning about the inevitability of death to a contemplation of the past and a sense of nostalgia.^[5]

Somehow, this erotic collection thread turned into a graduate seminar.
