Hi, Looks like in the answers there is a cheeky continuity correction that goes unmentioned?? Few specific follow-ups which I'd really appreciate some clarity on: 1) Why is continuity correction applied? 2) Most importantly - how do I know whether I am adding 0.5 or subtracting 0.5? 3) Can someone remind me when we do a correction of 0.5*n and when its just 0.5? Many thanks in advance, Dan
