I need help with my combination and permutation, I really appreciate everyones help!
Tell whether each problem represents a permutation or combination. Then solve the problem.
1. How many ways can you select 4 essay questions out of a total of 10 on an exam?
2. 6 children remain in a game of musical chairs. If 2 chairs are removed, how many different groups of students can remain?
3. How many ways can 3 flute players be seated in the first, second, or third seats in the orchestra?
.
4. In how many ways can 4 paintings be displayed from a collection of 15?
5. Given 12 Web sites, how many ways can you visit half of the sites?
Again, I appreciate everyones help. Thank you!
