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 ...

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).
