Quizplus · Accepted Answer

The intersection of any set with the empty set $\varnothing$ is always the empty set $\varnothing$, because there are no elements in common.

Let A={ June, Justine, Sally, Molly, Jello, Rachel }A = \{ \text { June, Justine, Sally, Molly, Jello, Rachel } \}A={ June, Justine, Sally, Molly, Jello, Rachel }

Let $A = \{ \text { June, Justine, Sally, Molly, Jello, Rachel } \}$
