During World War II, the allied forces attacked Germany. For the final assault, they had to cross a bridge. To fend off the attack, the Germans wanted to destroy the bridge, but not completely.

The Germans had 4 missiles with them and the firing conditions were as follows:

I.    Probability for the first missile to hit the target was 1/3. The probabilities of subsequent missiles to hit the target were 2/3, 3/4 and 4/5, respectively.

II.   Each missile had a limited destroying capability of 20%, 50%, 80% and 30%, respectively.

III.  Only two missiles hit the target on firing.

What is the probability of the Germans saving at least 30% of the bridge?
