Hello - I was curious about the origin of The Law of Total Probability, specifically who slated this law and when? Wikipedia provides an overview of TLTP but does not seem to provide any info about its origin?
In mathematics there are no laws
There are only axioms.
Look at this webpage..
"In 1933, Kolmogorov published his book, Foundations of the Theory of Probability, laying the modern axiomatic foundations of probability theory and establishing his reputation as the world's leading expert in this field."
So it looks like Kolmogorov defined this law/axiom in the 1930's?
