Answer 1

its a simple combination question.
from 14 articles he has to choose 9 and it does not matter which he chooses. so its just 14C9

Answer 4

Have you been introduced to combinations yet?

Answer 5

yes

Answer 6

Okay what differs from permutation and combination is that in permutation order matters. and in Combinations order does not matter. So in this case. the Journalist can choose any 9 articles of the 14 articles he has. so you have to use a calculator for this and there should be a key on it. "nCr" or \[C _{(n,r)}\] n is the total number of the something, and r is the number of choices. so for this question its simply 14C9=2002
