👉 In mathematics, a "posteriori" is a statement or proposition that follows from a given set of premises. It is often used in logical arguments to assert a conclusion based on the assumption that certain premises are true. For example, if we consider the following premises: 1. A person is born. 2. The Earth orbits the Sun. 3. All planets orbit the Sun. 4. All living organisms require oxygen for their survival. We can then say that "A person is born"
