I have to sets A={1,2,3} and B={a,b,c,d,e}. I want the set of subsets of elements from both A and B that contain at least one element of A and one element of B. I wanted to calculate it using the following formula:
P(A?B)?(P(A)?P(B))
I tried the following query:
Subsets[{1,2,3} union {a,b,c,d,e}]/(Subsets[{1,2,3}] union Subsets[{a,b,c,d,e}])
But, unfortunately, Wolframalpha doesn't understand my query.
Is there any other way?
