Intersect

Function: intersect (<a_1>, ..., <a_n>) intersect is the same as intersection, which see.

A : {1,2,3,4,5,6,7,10,15};
B : {4,5,6,7,8,9,10,a,b,d};
A1: cardinality(A);
B1:cardinality(B);
AUB1:cardinality(powerset(union(A,B)));
C:cardinality(intersect(A,B));
AUB2:cardinality(union(powerset(A),powerset(B)));
AU1: 2^(A1+B1-C);
AU2: 2^A1 +2^B1 -2^C

There are also some inexact matches for intersect. Try ?? intersect to see them.
