Barbara and Diane go target shooting. Suppose that
each of Barbara’s shots hits a wooden
duck target with probability
p
1
, while each shot of Diane’s hits it with
probability
p
2
. Suppose
that they shoot simultaneously at the same target. If
we learn that the wooden duck is
knocked over (indicating a hit), what is the
probability that
(a) both shots hit the duck?
(b) Barbara’s shot hit the duck?
What independence assumptions have you made?

Two marksmen shoot at a target simultaneously. Shooter A is known to have a 70% chance of hitting the target on any attempt. Person B has 40% accuracy. After the target is hit for the first time, it is revealed that A shot 5 shots while B shot 12. What is the probability that it was A who hit the target? What is the probability that person B hit the target? (Assume that accuracy of the shots remain the same...
2. Three weapons systems are shooting at the same target. From a design standpoint, each weapon has an equally likely chance to hitting the target. However in practice it has been observed that the precision of these weapons systems is not the same; that is, the first weapon usually hits the target 9 out of 12 shots, the second hits 8 out of 12, and the third hits 7 out of 12 shots. We observed that the target has been...
