Question

The union of sets P = {9, 10, 11, 12, 13} Q = {4, 5, 6, 7, 8} is given by which of the following?

{4, 5, 6, 7, 8}

{9, 10, 11, 12, 13}

ø

{4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

Answer 1

The union of two sets is the list of all members of the sets

We have set P = {9, 10, 11 , 12, 13} and set Q = {4, 5, 6, 7, 8}

The union of P and Q, P∩Q={4, 5, 6, 7, 8, 9, 10, 11, 12]
