Thank you so much :)

In designing an anti-aircraft gun it is important to know how many rounds should be red at the incoming aircraft so that the probability of hit is above a certain threshold. The aircraft can be shot down only if it is hit in a vulnerable spot and since the probability of hitting the spots with a single shot is extremely small, it is important to fair at them with a large number of shots. The probability of hitting an aircraft is 0.001 for each shot. How many shots should be red so that the probability of hitting with two or more shots is above 95%
