5. Two different colored fair dice are thrown. Let E1 be the event that the scores are both odd but different, and let E2 be the event that the sum of the scores is 8. Are the events E1 and E2 independent? (Note: You must justify your answer!)
How would i go about justifying?
Is my solution ok?
Even value in 1 to 6 are 2,4,6
Number of even value in 1 to 6 are 3
E1 = (3*2)/36 = 1/6
Odd value in 1 to 6 are 1,3,5
Number of odd value in 1 to 6 are 3
E2 = (3*2)/36 = 1/6
Yes, E1 and E2 are equal.
