By law of complementary probability and the definition of the output space of we have
P(X = 2) = 1 - P(X=1) right? The solution says P(X=2) = 1 - P(X=2)

Also when redefining X in terms of y, for value 2 it says 2, y in {1,2,3,4,5,6} but for 1 it says y <= 2. Should {1,2} be in the value 2? Shouldn't it just be {3,4,5,6} as it said previously?

I'm just a student but I think you're right.

I also agree with your points. I am just a student too. :)

Agree, it should be P(X = 2) = 1 - P(X=1)

[mcvillouta]

Same here, It should be P(X = 2) = 1 - P(X=1)
