The sets h and l are given below. =h, g, hj =l, a, dk find the intersection of h and l . find the union of h and l . write your answers using set notation.

The intersection of sets means what elements do they have in common.
For sets H and L the intersection would be the empty set because they have nothing in common. The notation for that is { }
The union means what are the elements in either set.
The union for H and L would be { g, h, j, a, k ,d }
