Law of total probability
In probability theory, the law (or formula) of total probability is a fundamental rule relating marginal probabilities to conditional probabilities.It expresses the total probability of an outcome which can be realized via several distinct events—hence the name.
Law Of Total Probability
The law of total probability is another probability law that gives you a way to reason about cases, which we’ve seen is a fundamental technique for dealing with all sorts of problems. So the point of cases, of course, is that you can prove a complicated thing by breaking it up into, if you’re lucky, easy sub cases.
Law of Total Probability – Statistics Part 19
 · Law Of Total Probability Let’s start with an example, if you have bought three pens, prices are P1 = Rs. 10,P2 = Rs. 20, P3 = Rs. 15, from the stationary and you, want to calculate the total money spent on the pens then what you will do, Total = P1+P2+P3 = 10
Total Probability Theorem
The Law of total probability is a law used to find the probability of an event when two events are mutually dependent. The total probability theorem relates the conditional probability with the marginal probability. In this law, the probability of an event can be calculated

Probability axioms
The Kolmogorov axioms are the foundations of probability theory introduced by Andrey Kolmogorov in 1933.[1] These axioms remain central and have direct contributions to mathematics, the physical sciences, and real-world probability cases.[2] An alternative approach to formalising probability, favoured by some Bayesians, is given by Cox’s
