**(i)** Given that,

X = {a, b, c, d},Y = {f, b, d, g}

To find, X−Y

The difference of the sets A and B in this order is the set of elements which belong to A but not to B.

X − Y = {a, b, c, d},- {f, b, d, g}

X – Y = {a, c}

**(ii)** Given that,

X = {a, b, c, d},Y = {f, b, d, g}

To find, Y−X

The difference of the sets A and B in this order is the set of elements which belong to A but not to B.

Y − X = {f, b, d, g}−{a, b, c, d}

Y – X = {f, g}

**(iii)** Given that,

X = {a, b, c, d},Y = {f, b, d, g}

X ∩ Y

The difference of the sets A and B in this order is the set of elements which belong to A but not to B.

X ∩ Y = {a, b, c, d},Y ∩ {f, b, d, g}

X ∩ Y = {b, d}
