Selection for jury duty is supposed to be a totally random process. Comment on the following computer selection procedures, and determine if they are indeed random:
a. A program instructs the computer to scan the list of names and pick names that were next to those from the last scan.
b. Three-digit numbers are randomly generated to select jurors from a list of licensed drivers. If the weight information listed on the license matches the random number, the person is selected.
c. The juror source list is obtained by merging a list of registered voters with a list of licensed drivers.
