Jeanine baker makes floral arrangements. she has 11 different cut flowers and plans to use 4 of them. how many different selections of the 4 flowers are​ possible?

Respuesta :

There are 330 different combinations.

[tex]_{11}C_4=\frac{11!}{4!7!} = \frac{11\times10\times9\times8}{4\times3\times2\times1}=330.[/tex]
