Close to 100%, if you wait long enough.

It is very likely that a comet has hit the earth in the distant past. It is possible that a comet striking the earth led to the extinction of the dinosaur.
A super comet is one that passes very closely to earths surface. It is said that if a super comet hit earth, it could wipe out existence as we know it.
It is too difficult to tell. There is no existing average for the velocity of comets, as all comets are different. Gravitional, solar and initial velocity have a lot to due with the velocity of a comet. Even though there is a great deal of variation, the answer would have to be very, very fast. Fast, that is, compared to earth standards. If a comet were to hit earth, for example, chances are that we wouldn't see or even know that it had hit. It would just hit. Not to scare you. The chances of a comet hitting the earth are slim to none.
We don't currently know when a comet will hit planet Earth.
Comet Lulin will not hit the Earth; it won't even come especially close.
No, a comet will NOT hit earth in 2012.
there will not be a comet in 2013 but there is a chance there could be but lets get back to the question it will only hit part of the world only part of the world will die or maybe it will hit us all but you never know
yes
we cant survive a comet and besides they dont hit the earth
10,000km
Depends on how big the Comet is.
maybe...
