The sample space when a fair dice is rolled is {1, 2, 3, 4, 5, 6}, with each outcome being equally likely. For which of the following pairs of events are the events independent?
The answer is {1, 2} and {1, 3, 4, 6}
But why? The solutions didn't make much sense to me, I don't understand where they got
Let A = {1, 2} and B = {1, 3, 4, 6}
Pr (A) = 1/3 and Pr (B) = 1/2
where'd that 1/2 come from?

No, wrong answer buddy. Its meant to be E, A = {1, 2} and B = {2, 4, 6}
You misread?

Get to bed anyway guys, it's really late!
Good luck! :D
No, sleep 3 am. Wake 10 am and leave 11 am. A good plan.
