Suppose you are firing at a target along a line, i.e., no
deflection error. Suppose the target you are shooting at is a
building running from X = -10 meters to X = 10 meters. The round
you fire has a random impact point that is Normally distributed
with a mean = 0 and a standard deviation of 40 meters. Suppose
there is a baby milk factory from X = 80 meters to X = 160 meters.
What is the probability that you hit the target? What is the
probability that you hit the baby milk factory? What standard
deviation (i.e., weapon accuracy) is required to reduce the
probability that you hit the baby milk factory to .00001 or
less?
