=====================================================框架
A random variable's possible values might represent the possible outcomes of a yet-to-be-performed experiment,less
or the possible outcomes of a past experiment whose already-existing value is uncertaindom
(for example, due to imprecise measurements or quantum uncertainty). 机器学习
They may also conceptually represent either the results of an "objectively" random process (such as rolling a die),ide
or the "subjective" randomness that results from incomplete knowledge of a quantity. post
The meaning of the probabilities assigned to the potential values of a random variable is not part of probability theory itself,学习
but is instead related to philosophical arguments over the interpretation of probability.优化
The mathematics works the same regardless of the particular interpretation in use !!!orm
