Question

How many combinations of four can you make from the set?

a rose, a daisy, a peony, a daffodil, a tulip

I figured since this is a combination, I would do 5C4, but I wasn't sure. Can someone give me some assurance on that? Thank you.

Answer 1

5c4 is good

Answer 2

Okay. Thank you.

Answer 3

does order count?

is rose daisy different or same as daisy rose?

Answer 4

^ should be.

Answer 5

It doesn't say order counts, but it put them in that order, so I don't know.

Answer 6

5C4 is correct

Answer 7

Do you guys still think 5C4?

Answer 8

combonation tends to mean order counts

Answer 9

okay.

Answer 10

if I have a lock, 4-13-6 is a different combonation than 13-6-4

Answer 11

True.

Answer 12

So, you work with the order they gave you? Therefore it's 5.

Answer 13

5C4*

Answer 14

id vote for it being a ambiguious question :)

Answer 15

Oh, and while I'm here, does "arrangement" have more to do with combinations or permutations?

Answer 16

unless the girl cares about which flower comes first, i'd say its 5c4 ;)

Answer 17

1 way.

how many ways can you and me stand in a row?

2 ways

Answer 18

Answer 19

Answer 22

I may need help with this.

Answer 24

Seven skiers enter a downhill race. First, second, and third places will be given to the three fastest skiers. How many arrangements of first, second, and third places are possible with seven skiers?

Answer 25

Maybe 7P3?

Answer 26

just for a memory check

4c0 4c1 4c2 4c3 4c4
1 4 6 4 1


4p0 4p1 4p2 4p3 4p4
1 4 12 24 24


does that sound right?

Answer 27

Yeah.

Answer 28

1st 2nd 3rd
7 * 6 * 5

Answer 29

So it is permutation, and 7P3?

Answer 30

7p3 for the skiers, yes

Answer 31

Alright, thank you for you help.
