# If X= { a, b, c, d } and Y = { f, b, d, g}, find (i) X – Y (ii) Y – X (iii) X ∩ Y

**Solution:**

The given sets are X= { a, b, c, d } and Y = { f, b, d, g}.

The difference between two sets A and B is a set denoted by A - B and is obtained by writing the elements of A that are NOT in B in a set. Thus,

**(i)** X - Y = {a, c}

**(ii)** Y - X = { f , g}

**(ii)** X ∩ Y = {b, d}

## If X= { a, b, c, d } and Y = { f, b, d, g}, find (i) X – Y (ii) Y – X (iii) X ∩ Y

**Summary:**

It is given that X = {a, b, c, d} and Y = {f, b, d, g}. We have found that

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