What is the equation for calculating the probability of intelligent life on other planets?

There are limits here as regards what characters can be posted. Use the link below to see the Drake equation. What the Drake equation is designed to calculate is the number N, where N is the number of civilizations in our galaxy with which communication might be possible. The equation is an interesting one, but it is full of variables over which any number of investigators can debate and attempt to agree on. In this light, the equation cannot yield a "number" that we can post and point to while saying, "That's how many planets have intelligent life on them that we can communicate with."

How many planets have people walk on?
Only the Planet Earth have humans walked on.
What is the maximum possible Mondays in one month?
5 mondays however this only applies on earth, depending on the planets orbit there could be more, for example: Saturn has an orbit of 10 759 earth days in a year, compared to earths 365 1/2 days per year. So taking into account there are 12 months in a "year" there are 896.58333333 days in a month. Therefore there can be over 128 "mondays in a month"
What is statistics as numerical facts?
Your question is very broad, but I will attempt to answer it, without entering into a philosophical question of statistics vs. facts. I have attached to related links. Sometimes a simple question does not have a simple answer. This is one of them. The term "fact" may have different meanings depending the context in which it is used. Facts may be different when they are: 1) Legal 2) Historical 3) Mathematical and 4) Scientific. The focus of this discussion is scientific facts verses statistics. Legal: Usually the "facts of a case" are elements of a legal case which neither party contests. This discussion does not relate to the use of facts as a legal term. Mathematics: An idea is a conjecture before it is proved, and then it becomes a proved theorem. The laws of addition, multiplication, etc are rigorously established. I can say, it is a fact that 2+2 = 4. This discussion of facts does not relate to the mathematical use of the words proof, theorems, laws or facts. Historical: Events which are witnessed by many and recorded are historical facts. Scientific facts: Relates to certain phenomena that is so well established, like the force of gravity, that scientists consider there is a natural law of gravity. The equations governing many natural phenomena have numerical constants. Now, statistics resulting from the collection of data assists in the scientific study of phenomena or processes. If certain physical numerical constants are identified through scientific study and approximated by reliable statistics through observations or experiments that can be duplicated by others, they may be considered "known constants"- which I would prefer to "numerical facts." Sometimes, our known facts change with more data- like the mass of some of our planets. Why is this important? Certain branches of science like physics and chemistry can through controlled experimentation identify physical constants. However, in other branches of science, like environmental science, the physical mechanisms are complex and measurement data is both scarce and variable. In these cases, science is advanced a combination of reliable statistics and known physical constants. You may want to investigate more on areas like global warming, ozone depletion or many social problems to identify statistics verses known physical constants.
What estimate does the drake equation give?
The Drake Equation is an interesting bit of wondrous speculation, that seeks to incorporate several reasonable statistical assumptions, that are based loosely on astronomical observations, into a single mathematical operation. The output of the operation is . . . The number of planets in our galaxy that are presently inhabited by technologically accomplished, intelligent civilizations.
Where can you find a reliable website with an equation calculating the number of planets with life in the galaxy?
Can't beat Wikipedia for most things. See related link for the Drake Equation"
Is there intelligent life on other planets?
So far, mankind has not discovered any life on other planets, let alone intelligent life. There's barely any intelligent life on this planet!!!
Do intelligent life exist on other planets?
No one knows
What is the mathematical probability that there is life on other planets?
Seeing as there are 344 discovered planets, and Earth is the only one with life, there is a 1/344 probability so far. the more planets discovered without life, the less the chances are that there could be life on them
Is there is an organization without people?
if there are other planets with intelligent life then certainly yes
Does the discovery of death on other planets contradict with religions?
No, most religious systems can accept the existence of intelligent life (and death) on other planets
Is their any life on any of the planets?
Well, certainly no intelligent life, anyway. (The only known life at this time is on Earth, which is one of the planets.)
Are there any planets beyond Pluto?
might be, i reckon there is hundreds of planets beyond Pluto full of intelligent lifeProbably lots - two of which are known and named ...but by the new classification they're are classed as dwarf planets.
What is the Drake Equation and what is its significance?
The Drake Equation was created by Dr. Frank Drake. It is used to test the probability of their being extra-terrestrial life. The equation is written as N = R x Fp x Ne x Fe x Fi x Fc x L. N is the number of civilizations in our galaxy where communication might be possible. R is the average rate formation per year in our galaxy. Fp is the fraction of those stars that have planets. Ne is the number of planets that can possibly support life. Fe is the fraction that can potentially develop life at some point. Fi is the fraction that can develop intelligent life. Fc is the fraction of civilizations that can develop technology that releases detectable signals into space. Finally, L is the length of time such civlizations release detectable signals into space.
Which among the planets in your solar system is the oldest?
In all probability, all the planets are about the same age. They formed around the same time as all of the other planets give or take a few million years.
Are alien's real and do they live on their own planet and have stuff like we do?
There are probably a billion stars in our galaxy, and probably a billion galaxies in the universe. We already know what there are planets orbiting many other stars; if there are planets around only 1% of the stars, that's still 100 billion planets. If only 1% of those planets are habitable, that's a billion habitable planets. If only 1% of those planets HAVE life, that's 10 million planets with life. If only 1% of the planets that have life have highly-developed life forms, then there are 100,000 planets with highly developed life forms. If only 1% of those planets have intelligent life, that's still 1,000 planets in the universe that have intelligent life; "aliens". We have NO IDEA if there are any other planets that have life, or intelligent life in the universe, or if those aliens - if any exist - might be willing or able to communicate with us. But I would like to think so.
