Jeanine Baker makes floral arrangements. She has 15 different cut flowers and plans to use 5 of them. How many different selecti
AlladinOne [14]

For the first flower she has a choice of 15. For the second 14 (15 minus the one that was already used). For the third 13, and so on.

Each of the first 15 can be match with any of the second 14. Any of the first pairs can be matched with ant of the third 13 and so on.

This gives us

Number of Selections = Choices for Flower 1 x Choices for Flower 2 x Choices for Flower 3 x Choices for Flower 4 x Choices for Flower 5

N_{s}=f_{1} \times f_{2} \times f_{3} \times f_{4} \times f_{5}

N_{s}=15 \times 14 \times 13 \times 12 \times 11

N_{s}=360,360


You could also calculate this as the permutation _{15}P_{5}=\frac{15!}{(15-5)!}
