Ifx = {abc} , Y = { b, c, d } findAx B and BX A​

Answer»

Step-by-step explanation:

GIVEN SETS are :

x = {a,B,C} ,

Y = { b, c, d }

X×Y={a,b,c}×{b,c,d}

=>{(a,b),(a,c),(a,d),(b,b),(b,c),(b,d),(c,b),(c,c),(c,d)}

Y×X={b,c,d}×{a,b,c}

=>{(b,a),(b,b),(b,c),(c,a),(c,b),(c,c),(d,a),(d,b),(d,c)}

X×Y≠Y×X
