What does it mean when the weather forecast says that there is a 60% chance of rain?
If the weather forecast shows a 60% chance of rain for today, does that mean that in all of (say) London, there is a 60% chance that there will be a drop of rain today? or 5 mm of rain, or how much? Or maybe 60% of London will see rain today? Or is the duration of the rainfall important?
