What's the probability of an event happening exactly once after two independent trials? It's actually a made-up problem to understand this basic concept, so that I could do a more complex homework problem. :) Your hints could go both ways in my mind: "it doesn't matter" could be in the sense that "we should account for both" (2nd option) or "we are already accounting for both (1st option). |
