Question

2. Let A = {1,2,3} and
B = { is a prime number less than 10}. Find AXB and BXA.​

Answer 1

Answer:

Step-by-step explanation:

AxB = {(1, 2), (1, 3), (1, 5), (1, 7), (2, 2), (2, 3), (2, 5), (2, 7), (3, 2), (3, 3), (3, 5), (3, 7)}

BxA = {(2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3), (5, 1), (5, 2), (5, 3), (7, 1), (7, 2), (7, 3)}

A = {1,2,3}

B = {2,3,5,7}
