Measure theory | Families of sets
In mathematics, a π-system (or pi-system) on a set is a collection of certain subsets of such that * is non-empty. * If then That is, is a non-empty family of subsets of that is closed under non-empty finite intersections.The importance of π-systems arises from the fact that if two probability measures agree on a π-system, then they agree on the 𝜎-algebra generated by that π-system. Moreover, if other properties, such as equality of integrals, hold for the π-system, then they hold for the generated 𝜎-algebra as well. This is the case whenever the collection of subsets for which the property holds is a 𝜆-system. π-systems are also useful for checking independence of random variables. This is desirable because in practice, π-systems are often simpler to work with than 𝜎-algebras. For example, it may be awkward to work with 𝜎-algebras generated by infinitely many sets So instead we may examine the union of all 𝜎-algebras generated by finitely many sets This forms a π-system that generates the desired 𝜎-algebra. Another example is the collection of all intervals of the real line, along with the empty set, which is a π-system that generates the very important Borel 𝜎-algebra of subsets of the real line.

More important than knowing a bunch of digits in the decimal approximation of Pi is to understand what Pi means. Pi is the ratio of the Circumference to the Diameter of any circle. Multiply the diameter by Pi to get the circumference or divide the circumference by pi to get the diameter.

Pi is defined as the ratio of the circumference of a circle to its diameter. A frisbee is used to show the definition of pi. The units for pi, radians, are discussed. The conversion factor between revolutions, degrees, and radians is introduced. Want Lecture Notes? http://www.flippingphysi

A random approximation for Pi (pi day short)
In this short, we randomly sample 5000 pairs of positive integers and use the pairs to plot points in the plane. If a pair is relatively prime, we shade the dot red; otherwise we shade the dot blue. The theory behind this process says that roughly 6/pi*pi of the dots will be red. So we can
