Probability of A and B both occuring: P(AB), Probability that A or B or both occur: P(AB), Probability that A or B occurs but NOT both: P(AB), Probability of neither A nor B occuring: P((AB)'), Probability of event that does not occurs P(A'). The formula for working out an independent probability is quite simple: P(A) equals Probability of any event occurringN is the Number of ways an event can occur and0 is the total number of possible Outcomes. You're absolutely right, and we have corrected the article to say "at least one of the two dice." Yeah, this happens, you know, its called blind luck.
