Can an event be truly random?
No, it is only random in the practical game-playing situation you describe. In physics theory it would just be a classical set of movements and would not be random. A truly random process is no more obtainable in Physics than Infinity or Zero. Randomness is a mathematical concept and Maths is based on axioms.
Do random events have to be equally likely?
Randomness does not mean equal probabilities of occurrence for each element of a sample space (of a set of outcomes). An event is random if its outcome is unknown beforehand, in the simplest terms. It can’t be partially unknown.
What is a true random event?
In a very liberal sense, random is just something that is unpredictable. A fair coin toss, then, is sufficiently random. The problem comes in when you try to apply a more strict definition of random; perhaps an event is truly random when the probability of the possible outcomes is equal.
Is life just a series of random events?
Yes, you read that right, folks. Here’s what I learned: Life is a random process, just like a statistical time series. There are areas of life within our control, and there is randomness out of our control. Life goes up, life goes down, much of it due to random chance in the world.
Why is randomness important in life?
Without randomness, there would be so many unsolved problems thus this process is essential. Nevertheless, this raises the question of fairness. Many would love to know whether this process is fair. Those who are opposed to randomness should offer amicable ways of solving problems of this sort.
Is there a purpose in life?
All life forms have one essential purpose: survival. This is even more important than reproduction.
What other situations in real life seem to happen randomly?

Can you prove randomness?
Randomness tests with only data as input can mathematically and thus conclusively prove non-randomness, but not vice versa. It is impossible to prove that a chain of numbers you’re given is truly random without further information about how they came to be.
Does randomness have a pattern?
A random sequence of events, symbols or steps often has no order and does not follow an intelligible pattern or combination. Individual random events are, by definition, unpredictable, but if the probability distribution is known, the frequency of different outcomes over repeated events (or “trials”) is predictable.
Is there randomness in the universe?
With randomness in Nature, the universe could not have been predetermined completely in the sense that it should be impossible in principle to compute from the big bang or at any later moment whether live and conscious observers might or might not appear there.
Why do we see patterns in randomness?
Because there is no process that's trying to space them apart.
What causes randomness?
Randomness and unpredictability arise from the absence of rules. This source of randomness is, however, ideal if not trivial. In the mathematical system and in the physical world there is always some kind of an underlying rule(s).
Do physicists believe in randomness?
Physicist: With very few exceptions, yes. What we normally call “random” is not truly random, but only appears so. The randomness is a reflection of our ignorance about the thing being observed, rather than something inherent to it.
What is the difference between randomness and chaos?
Randomness, like cards or dice, is unpredictable because we just don’t have the right information. Chaos is somewhere between random and predictable. A hallmark of chaotic systems is predictability in the short term that breaks down quickly over time, as in river rapids or ecosystems.
What is chaos theory in simple terms?
Chaos theory describes the qualities of the point at which stability moves to instability or order moves to disorder. For example, unlike the behavior of a pendulum, which adheres to a predictable pattern a chaotic system does not settle into a predictable pattern due to its nonlinear processes.
What is chaos theory philosophy?
Specifically, chaos theory suggests that the behavior of complex systems can follow laws and yet their future states remain in principle unpredictable. The behavior of complex systems is exquisitely sensitive to conditions, so that small changes at the start can result in ever larger changes over time.
What is stochastic theory?
Stochastic theories model systems which develop in time and space in accordance with probabilistic laws. ( The space is not necessarily the familiar Euclidean space for everyday life. We distinguish between cases which are discrete and continuous in time or space.
What is the difference between stochastic and random?
Stochastic means nondeterministic or unpredictable. Random generally means unrecognizable, not adhering to a pattern. A random variable is also called a stochastic variable.
What is the difference between stochastic and deterministic events?
A deterministic system is a system in which no randomness is involved in the development of future states of the system. A stochastic system has a random probability distribution or pattern that may be analysed statistically but may not be predicted precisely.
What is the difference between stochastic and probabilistic?
In general, stochastic is a synonym for probabilistic. For example, a stochastic variable or process is probabilistic. It can be summarized and analyzed using the tools of probability. Most notably, the distribution of events or the next event in a sequence can be described in terms of a probability distribution.
Can a stochastic event be a random variable independent of itself?
The only way a random variable X can be independent of itself is if for every measurable set A, either Pr(X∈A)=1 or Pr(X∈A)=0.
What is the opposite of stochastic?
The opposite of stochastic modeling is deterministic modeling, which gives you the same exact results every time for a particular set of inputs.
Is stochastic process random process?
In probability theory and related fields, a stochastic (/stoʊˈkæstɪk/) or random process is a mathematical object usually defined as a family of random variables. Stochastic processes are widely used as mathematical models of systems and phenomena that appear to vary in a random manner.
How hard is stochastic processes?
Stochastic processes have many applications, including in finance and physics. It is an interesting model to represent many phenomena. Unfortunately the theory behind it is very difficult, making it accessible to a few ‘elite’ data scientists, and not popular in business contexts.
What is strictly stationary process?
In mathematics and statistics, a stationary process (or a strict/strictly stationary process or strong/strongly stationary process) is a stochastic process whose unconditional joint probability distribution does not change when shifted in time.
Who invented stochastic calculus?
Professor Kiyosi Ito
Professor Kiyosi Ito is well known as the creator of the modern theory of stochastic analysis. Although Ito first proposed his theory, now known as Ito’s stochastic analysis or Ito’s stochastic calculus, about fifty years ago, its value in both pure and applied mathematics is becoming greater and greater.
Is stochastic calculus math or statistics?
Stochastic calculus is a branch of mathematics that operates on stochastic processes. It allows a consistent theory of integration to be defined for integrals of stochastic processes with respect to stochastic processes.
What does raw stochastic mean?
Raw stochastic – the most basic value representing the stochastic value for each period. Also known as raw K. %k – the first smoothing of the raw stochastic, usually with a 3-period exponential moving average.
What is an SDE math?
A stochastic differential equation (SDE) is a differential equation in which one or more of the terms is a stochastic process, resulting in a solution which is also a stochastic process. SDEs are used to model various phenomena such as stock prices or physical systems subject to thermal fluctuations.
Do you need measure theory for stochastic calculus?
Summary. Integration of Brownian motion opens the door to powerful calculus-based modeling tools, such as stochastic differential equations (SDEs). Stochastic calculus is an advanced topic, which requires measure theory, and often several graduate-level probability courses.
What is stochastic process in statistics?
A stochastic process means that one has a system for which there are observations at certain times, and that the outcome, that is, the observed value at each time is a random variable.
