How is measure theory used in probability?
Measure Theory is the formal theory of things that are measurable! This is extremely important to Probability because if we can’t measure the probability of something then what good does all this work do us? One of the major aims of pure Mathematics is to continually generalize ideas.
How can you measure probability?
Divide the number of events by the number of possible outcomes.
- Determine a single event with a single outcome.
- Identify the total number of outcomes that can occur.
- Divide the number of events by the number of possible outcomes.
- Determine each event you will calculate.
- Calculate the probability of each event.
What is measure theory used for?
Measure theory is the study of measures. It generalizes the intuitive notions of length, area, and volume. The earliest and most important examples are Jordan measure and Lebesgue measure, but other examples are Borel measure, probability measure, complex measure, and Haar measure.
Why do we need measure theory in probability?
So measure gives us a way to assign probability to sets of event where each individual event has zero probability. Another way of saying this is that measure theory gives us a way to define the expectations and pdfs for continuous random variables.

What is a measurement theory?
Measurement theory is a branch of applied mathematics that is useful in measurement and data analysis. The fundamental idea of measurement theory is that measurements are not the same as the attribute being measured.
What is possibility theory?
Possibility theory is a mathematical theory for dealing with certain types of uncertainty and is an alternative to probability theory. Professor Lotfi Zadeh first introduced possibility theory in 1978 as an extension of his theory of fuzzy sets and fuzzy logic.
