Question

If P = {1, 2, 3) and Q = {4}, find sets PxQ and QxP.

Answer 1

Answer:

P x Q  = { (1, 4), (2, 4), (3, 4)}

Q x P  =  {(4, 1), (4, 2), (4, 3)}

Step-by-step explanation:

Hi,

Given P = {1, 2, 3} and Q = { 4}

Cartesian Product of sets P and Q will consists of all ordered

pairs such that the first element s picked from set P and the

second element s picked from the second set Q.

So, P x Q = { 1, 2, 3} x { 4}

= { (1, 4), (2, 4), (3, 4)}

Similarly Q x P

= {4} x { 1, 2, 3}

= {(4, 1), (4, 2), (4, 3)}

Hope, it helps !
