Answer 1

If set X = {2, 4, 6} and set Y = {2, 4, 6, 8} the chart below shows the union and intersection of these sets.

Answer 2

Of the 15 students in drama class, five want to perform a musical, seven want to perform a play, and nine want to perform their own monologues. Some of the students voted for more than one type of presentation.
The three choices above represent sets. One set is composed of students who voted for the musical, one set is students who voted for a play, and one is students who voted for monologues. Some students belong to more than one set since they voted for more than one activity. There is an intersection between these sets since they have some members in common.
