1. The problem statement, all variables and given/known data I need to get the CHSH inequality from Bell's inequality 2. Relevant equations |C(a, b) - C(a, b')| + |C(a', b) - C(a', b')| <= 2 to -2 <= C(a, b) - C(a, b') + C(a', b) + C(a', b') <= 2 3. The attempt at a solution I know the CHSH allows for no correlation of 0 but I can't get anywhere. I think my math with inequalities just sucks.
