Question

Patty has 8 flowerpots, and she wants to plant a different type of flower in each pot. There are 11 types of flower available at the garden shop. How many different ways can choose the flowers?

Answer 1

The combination formula is given by

C(n, r) = $\frac{n!}{(n-r)!r!}$

C(11, 8) = $\frac{11!}{(11-8)!8!}$

C(11, 8) = 165

So, there are 165 ways of choosing 8 flowers out of 11 flowers
