Problem

The three targets from a rifle range shown below were produced by: (A) the instructor firing a newly acquired target rifle; (B) the instructor firing his personal target rifle; and (C) a student who has fired his target rifle only a few times.

The figure shows three targets from a rifle range labeled from (a) to (c). In target (a), all bullet holes are located at the top right part closely to each other. In target (b), all bullet holes are located at the center of the target closely to each other. In target (c), bullet holes are scattered randomly with a great distance between the holes.

Comment on the accuracy and precision for each of these three sets of results.
