Assume there are three subsets X, Y, Z of some universal set U.

| X u Y u Z | = 41
| X | = 20
| Y | = 28
| Z | = 21

| X n Y | = 12
| X n Z | = 10
|Y n Z | = 11
|X-| = 24 (bar over top of X).

Solve:

a) | X u Y |

b) | Y △ Z |

c) | X n Y n Z |

d) |Y - (X u Z) |

e) | U |

f) |X n Y n Z | (one bar over both X and Y).
