For each of the following situations, explain why the combinations rule or the permutations rule should be used.
(a)Determine the number of different groups of 5 items that can be selected from 12 distinct items.
Use the combinations rule, since the number of arrangements within each group is of interest.
Use the permutations rule, since the number of arrangements within each group is of interest.
Use the combinations rule, since only the items in the group is of concern.
Use the permutations rule, since only the items in the group is of concern.
