    Or is not exclusive, so every element that is in B or is in C should be counted. That includes ones that are in A if they are also in at least one of B or C.

    The answer you are looking for is 52. The list I made above shows the groups of elements that are included in subset B, subset C, or both. Summing those groups up, you get 52.
