  • $\begingroup$ I just found this in Wikipedia: For functions A(x) and B(x), A(x) ∨ B(x) is used to mean max(A(x), B(x)). Is it possible that what the author means is this? $\endgroup$

  • $\begingroup$ I think Did is right: en.wikipedia.org/wiki/List_of_mathematical_symbols. I guess, the point of all this chapter would be clearer, if you just google for "law of rare events", e.g. see this: en.wikipedia.org/wiki/…. Resnick's notation doesn't allow the reader to recover the meaning from it. $\endgroup$ Jan 22, 2014 at 6:24

$$\bigvee_{1\leqslant k\leqslant n}p_k(n)=\max_{1\leqslant k\leqslant n}p_k(n)$$ $$\bigwedge_{1\leqslant k\leqslant n}p_k(n)=\min_{1\leqslant k\leqslant n}p_k(n)$$
