Question

Ms. Chang has 16 students in her class. She wants to send 3 of her students to pick up books for the class. How many combinations of students can she choose?

A. 48
B. 250
C. 560
D. 3360

Answer 1

I think the answer is B.

Answer 2

(C) 560

Explanation:

Total students = 16

Number of students to send = 3

Since the position is not important,

Number of combination

= (16 x 15 x 14) / (1 x 2 x 3)

= 3360/6

= 560
