Answer:
B. 35
Step-by-step explanation:
The order in which the flowers are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
4 flowers from a set of 7. So
[tex]C_{n,x} = \frac{7!}{4!(7-4)!} = 35[/tex]
The correct answer is given by option B.
