Question

Given X = {a, b, f} and Y = {b, c, f, g}, what is XY?

Answer 1

y - x (elements in y but not in x):

y - x = {f, g}

Given sets:

x = {a, b, c, d}

y = {f, d, b, g}

x - y (elements in x but not in y):

x - y = {a, c}

y - x (elements in y but not in x):

y - x = {f, g}

Question

If x={a,b,c,d} and y={f,d,b,g} then find x-y and y-x​
