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?
