Since order doesn't matter, we can simply use the combination notation cited as:
, where n represents the number of objects and r represents the number of subsets.
If we were to choose 3 books from a pack of 5, we can choose them in

To keep rabbits away from lettuce garden, she need to set up chicken wire along the garden's circumference. If circumference comes out to be > 20 feet, then yes she will have enough chicken wire to surround the garden. If not , it will be food fest for rabbits. LoL!
Anyways,
Circumference of lettuce garden = pi x diameter of garden
= 3.14 x 6 = 18.84 feet.

So she will be left with 1-2 feet of wire.
Better luck for the next time Mr. Bunny :D
