How would you justify these answers?

Can someone do a more simple step way of doing these solutions?

Thanks

Two different colored fair dice are thrown. Let E1 be the event that the scores 5. differ by 4, and let E2 be the event that the sum of the scores is 4. Are the events E1 and E independent? (Note: you must justify your answer!) -{(1,3), (2,2), (3, 1)} Isl 36 12 E, and E, are not independent
