Tolong jelaskan mengenai Lemmas in probability dari Probability axioms dalam bahasa sunda

From the Kolmogorov axioms one can deduce other useful rules for calculating probabilities:

That is, the probability that A or B will happen is the sum of the

probabilities that A will happen and that B will happen, minus the

probability that A and B will happen.  This can be extended to the inclusion-exclusion principle.

That is, the probability that any event will not happen is 1 minus the probability that it will.

Using conditional probability as defined above, it also follows immediately that

That is, the probability that A and B will happen is the probability

that A will happen, times the probability that B will happen given

that A happened; this relationship gives Bayes' theorem. It then follows that A and B are independent if and only if
