*only the 4th, sorry.

See, 4th question is an independent event. We see that 1/3 is the probability to answer it correctly. Answer is the third option.

This question has confused everyone for ages! Hope I have ENLIGHTENED YOU :P

@ParthKohli , you actually mostly just gave the answer.

parthkohli · Answer

Okay, 4th question has no connection with other questions. And the probability to answer correctly is ${1 \over 3}$ because our preferred number of outcomes(1) over number of possible outcomes(3) would be the probability.

@ParthKohli , that's much better. But, unfortunately this user is obviously just an ask answer user.
