The probability that a bomb dropped on a bridge hitting it is 0.5. Eight bombs are dropped on the bridge. The bridgewill be destroyed if any two bombs fall on it. Find the probability that:i) All bombs hit the bridge

If the probability that a bomb will hit a target is 60% and if 10 bombs are dropped then find mean and variance.

Assume that the probability that a bomb dropped from an aeroplane will strike a certain target is 0.2. If 6 bombs are dropped find the probability that (i) exactly 2 will strike the target.(ii) at least 2will strike the target.

Assume that the probability that a bomb dropped from an aeroplane will strike a certain target is 0.2. If 6 bombs are dropped find the probability that (i) exactly 2 will strike the target. (ii) at least 2 will strike the target.

The probability that a bomb will miss a target is 0.2. The probability that out of 5 bombs dropped, exactly 4 will hit the target is

The probability of a bomb hitting a target is 0.2. Two direct hits are necessary to destroy a bridge. If six bombs are aimed at the bridge, find the probability that the bridge is destroyed.

In a bombing of the Nathula pass, the Indian troops have to destroy a bridge on the pass. The bridge is such that it is destroyed when exactly 2 bombs hit it. A MIG-27 is dispatched in order to do the bombs hit it. A MIG-27 is dispatched in order to do the bombing. Flt Lt. Rakesh Sharma needs to ensure that there is at least 97% probability for the bridge to be destroyed. He knows that when he drops a bomb on the bridge the probability of the bomb hitting the bridge is 90%. Weather conditions and visibility being poor he is unable to see the bridge from his plane. How many bombs does he need to drop to be 95% sure that the bridge will be destroyed?

The probability that a bomb will hit a target is 0.8. The probability that out of 10 bombs dropped, exactly 2 will miss the target is

The probability that a bomb dropped from a plane strikes the target is 1//5 . The probability that out of six bombs dropped at least 2 bombs stricke the target is

The probability that a bomb dropped from a plane strikes the target is 1//5 . The probability that out of six bombs dropped at least 2 bombs stricke the target is
