To be sure of 2 light chocolates, 9 would need to be chosen as you would first need to eliminate the 7 dark chocolates and then pick the extra 2 light ones. For the 2 dark, 11 would bee needed as, again, the 9 lights would need to be eliminated and the other 2 dark accounted for.

∠1 is an angle formed by the two lines PF and YF at point F
We can also call this angle as ∠PFY because it indicates the point F in the middle where the angle is formed
We can call this angle as ∠YFP because it also indicates the point F in the middle where the angle is formed
we can also call this angle ∠F since F is the point where the angle is formed.
Correct answer: ∠PFY, ∠YFP, ∠F

Or C(x) if they want you to be more specific.
x is your independent variable.
Miles driven do not depend on anything.
