In Left 4 Dead there is cool move when 4 hunters land on 4 different targets resulting in instant win.

I did some statistic research against good teams to find out how much hunters fail.

- There is 0.8 chance that hunter will get shot during the jump.
- There is 0.6 chance that hunter will get stopped after the jump.
- There is 0.6 chance that hunter will jump on wrong target(which makes whole attack fail).

So to make successful attack all 4 hunters must not get shot during the jump, must not get stopped if didn't got shot during the jump, must jump on right target.

How do I eliminate all failures and find out success probability?
