5/18/2023 0 Comments Simple math problems with answers![]() Rice weighing 3 3/ 4 pounds was divided equally and placed in 4 containers. This means that at least one of the probabilities must be extremely low.(a) -1, (b) -1/2, (c) 0, (d) 3. ![]() Since the number of planets in the galaxy is in the hundreds of billions, even very small values of the three probabilities would imply that we should see many interstellar civilizations. The probability that any given interstellar civilization would be detectable from Earth at this time The probability that any given intelligent species develops an interstellar civilization ![]() The probability that any given planet produces intelligent life The expected number of interstellar civilizations observable from Earth is the product of the number of planets in the galaxy and the following three probabilities: It is far deeper than a simple math challenge. The solution to this paradox has implications for how we percieve the likelihood of us surviving as a civilization. The Fermi Paradox refers to the tension between estimates suggesting our galaxy is likely to harbor many interstellar civilizations and the fact that we have observed no such civilizations.
