The math is correct - we did this in my stat class.

Assume that you have X dollars in cup A, and cup B has either 1/2 as much or twice as much.
Expected value from choosing cup B is (1/2)(1/2) * (2)(1/2) = 1.25

Therefore, repeating the same math for choosing cup A is also 1.25

So no matter which one you choose, you stand to gain more value by choosing the other.
