1 over 64
8^2 = 64 , 8^-2 = 1/(8^2) = 1/64
Your answer would be the last option, D.
This is because spinning the spinner does not affect which marble you pick, as these are mutually exclusive events. This means that if the spinner lands on red, you could choose a black or white marble, and if the spinner lands on green you could also choose a black or white marble.
The only sample space that represents this is D because it's the only one that includes both black and white options after spinning red and green.
I hope this helps!
You can factor this out by thinking of the factors of 56 that have a sum of -1. 7 and 8 are factors of 56 and to get a sum of -1, 8 should be negative. 7 + -8 = -1
So

factored out is (y+7x)(y-8x)
We can check this using FOIL
F = (y)(y) =

O = (y)(-8x) = -8xy
I = (7x)(y) = 7xy
L = (7x)(-8x) =
