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?

 
1/60
1/10
1/20
1/30

As the Germans have to save at least 30% of the bridge, they can destroy at most 70% of it. Also, as 2 missiles have to hit the target, these conditions will be only obtained in the following 2 cases:
rnCase 1: Missiles 1 and 2 hit but 3 and 4 dont
rnThe probability of this happening is 1/3 x 2/3 x 1/4 x 1/5 = 1/90
rnCase 2: Missiles 1 and 4 hit their mark and 2 and 3 dont
rnThe probability of this happening is 1/3 x 1/3 x 1/4 x 4/5 = 1/45
rnThus, the total probability = 1/90 + 1/45 = 1/30
rnHence, answer option 4 is correct.
