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).
