The error function is widely used in probability theory, theory of errors, and various branches of mathematical physics. The error function is defined by the integral 2 erf(t) ,-x² dx. Evaluate the following nonlinear integral transforms after changing the order of integration 00 00 e-pt erf(t) dt and e-pt erf(1/vE) dt

Counting Principles

In statistics, the counting principle can be said to be the concept in which the quantity of an item is determined. There can be a single item, or a group of items, or items that are related to each other. In every possible set of items, the quantity of the possible item groups or their sorting measures can be determined with counting principles.
