I'm not English. I can't understand this sentence: "...how small the probability of an event ought to be in order that we can consider it to be impossible and of insignificant consequence to the undertaking at hand."
at hand? how to understand this? for one person?
Top answer
Something is at hand means it is close in some way. eg When I sit at my desk, my dictionary is always at hand. eg The US election is at hand.
