Question 1:
My question is how do I know when to use the permutation theorem or comination theorem?
Theorem in paint document
I'm asking because I would have used permutation thm. on 46 but I was wrong.
Problem 46 b. and Problem 47 a. seem similar. The two main differences that I see are
1. 46. We are given a group of ten people to choose from
47. We are given a group of six people to choose from
2. 46. Placement of bride and groom does not matter (Bride and groom must be in picture No reference to placement)
47. Placement of bride and groom matters (Bride must be next to groom)
Therefore do I use combination if Placement matters?
And permutation if placement does not matter?
Question 2:
How would the answer to 46 b change if bride must be next to groom?
and
how would answer to 47 a change if bride and groom must be in picture?
