beating someone up

[navi tasan]

Is this sentence correct:
1) Let's say that there is ten percent probability of serious injury as a result of beating someone up.

Obviously, the person who is beaten up will sustain the serious injury, not the one who is doing the beating up!

Gratefully,
Navi.

The sentence is ambiguous. There is usually a risk to both unless weapons are used.

The sentence says that if I beat someone up, there's a ten-percent chance I'll suffer a serious injury.

The sentence says that if I beat someone up, there's a ten-percent chance I'll suffer a serious injury.

That doesn't follow from the construction of the sentence though.
"There's a ninety percent probability of collateral damage as a result of dropping a bomb on an enemy stronghold." What does this one mean?

It is theoretically ambiguous, but the person who is beaten up is generally the one that suffers the greater injuries, so I would assume that the logical interpretation is that sentence refers to the victim. I think that the person would probably have made it more specific if referring to the person doing the beating.
