The normal distribution assumption and other assumptions.
mason.gmu.eduKolmogorov test - better for larger samples. (The division is not clear cut, and there's lots of overlap). ... For a two-sample test, if each sample is 20 to 25 or over that is often good enough. But it depends on how non-normal the data is. If the data are strongly non-normal, you might need a larger sample size, say 50 or even ...

Chapter 5 An Introduction to Discrete Probability
www.cis.upenn.eduBecause events are subsets of the sample space W, they can be combined using the set operations, union, intersection, and complementation. If the sample space W is finite, the definition for the probability Pr(A) of an event A W given in Definition 5.1 shows that if A,B are two disjoint events (this means that A\B= 0),/ then Pr(A[B)=Pr(A)+Pr(B).
