What is a Probability is used to estimate probabilities by making certain assumptions about an experiment?
Gwerth Probablitiy
How are experimental probability and theoretical experiment alike?
They are both estimates of the probability of outcomes that are of interest. Experimental probabilities are derived by repeating the experiment a large number of times to arrive at these estimates whereas theoretical probabilities are estimates based on a mathematical model based on some assumptions.
What are the requirements for probability distribution?
(1) That the probabilities lie between 0 and 1. (2) The sum of all probabilities of the distribution sum up to 1.
What is the sum of all probabilities?
Sum of all probabilities is 1.
What is the sum of the probabilities of all possible outcomes?
The sum of the probabilities of all possible outcomes is 1.

What is the difference between assumptions and personal jugement?
assumption is objective and personal judgment is subjective
The difference between an empirical distribution and a theoretical distribution?
Empirical Distribution: based on measurements that are actually taken on a variable. Theoretical Distribution: not constructed on measurements but rather by making assumptions and representing these assumptions mathematically.

What is the difference between theoretical probability and empirical probabilities?
empirical probability is when you actually experiment with it and get data values, and theoretical probability is when you use math to make an educated guess.
What is the difference between axiom and theorem?
The axioms are the initial assumptions. The theorems are derived, by logical reasoning, from the axioms - or from other, previously derived, theorems.
What is the difference between 'stochastic' and 'probabilistic'?
I think most people use them as synonyms. In general usage, it can be appropriate. However, a probabilistic approach describes the occurrence of deterministic states with given probabilities, while stochastic processes are built up by sequential steps occurring with given probabilities. Think of the difference between throwing a die once which determines the state you will arrive at and throwing a die multiple times where the resulting states are (can be) dependent on the previous states.

(1) That the probabilities lie between 0 and 1. (2) The sum of all probabilities of the distribution sum up to 1.
what is the difference between prior and posterior probability?
A posterior probability is the probability of assigning observations to groups given the data. A prior probability is the probability that an observation will fall into a group before you collect the data. For example, if you are classifying the buyers of a specific car, you might already know that 60% of purchasers are male and 40% are female. If you know or can estimate these probabilities, a discriminant analysis can use these prior probabilities in calculating the posterior probabilities. When you don't specify prior probabilities, Minitab assumes that the groups are equally likely.
What has the author A A Markov written?
A. A. Markov has written: 'Differenzenrechnung' -- subject(s): Difference equations, Interpolation 'The Correspondence between A.A. Markov and A.A. Chuprov on the theory of Probability and Mathematical statistics' -- subject(s): Correspondence, Mathematical statistics, Mathematicians, Probabilities '[Izbrannye trudy' -- subject(s): Bibliography, Number theory, Probabilities
All probabilities are expressed as a number between the range of?
0- less than1
Can -0.5 be a probability?
No. Probabilities are 'counted' as between 1 (certain) and 0 (impossible)
