Question
(Set Operations and Relations MC)Given A = {3, 6, 8} and B = {4, 8}, find B × A. {(3, 4), (6, 4), (8, 4)} {(4, 3), (4, 6), (4, 8), (6, 4), (8, 4)} {(3, 4), (3, 8), (6, 4), (6, 8), (8, 4), (8, 8)} {(4, 3), (4, 6), (4, 8), (8, 3), (8, 6), (8, 8)}
Solution
The Cartesian product of two sets B and A, denoted by B × A, is the set of all ordered pairs (b, a) where b is in B and a is in A.
Given B = {4, 8} and A = {3, 6, 8}, we can find B × A by pairing each element of B with each element of A.
So, B × A = {(4, 3), (4, 6), (4, 8), (8, 3), (8, 6), (8, 8)}.
Therefore, the correct answer is {(4, 3), (4, 6), (4, 8), (8, 3), (8, 6), (8, 8)}.
