Question

what does it mean by mutually disjoint sets give example

Answer 1

in mathematics, 2 sets are said to be disjoint set if they have no element in common. Equivalently,disjoint sets are sets whose intersection is the empty set

eg . (1,2,3)and (4,5,6) are disjoint sets

but (1,2,3)and (3,4,5) are not disjoint sets
