region, or explain why the conditions are impossible to meet.

Select the correct choice below and fill in any answer boxes within your choice.

O A. The number of elements in regions I, II, III, IV, V, VI, VII, VIII are

, respectively.

O B. It is impossible to meet the conditions because there are only

elements in set

A but there are

elements in set A that are also in set B or C. A similar

problem exists for set C. (Simplify your answers.)

O C. It is impossible to meet the conditions because there are only

elements in set

B but there are

elements in set B that are also in set A or C. A similar

problem exists for set C. (Simplify your answers.)

17. Determine whether the following statement is true or false. If the statement is false, make the necessary change to

produce a true statement.

If An B=Ø, then n(AUB) = n(A) + n(B).

Choose the correct answer below.

O A. The statement is false. If An B= Ø, then n(A U B) = n(A) – n(B).

B. The statement is false. If An B= Ø, then n(A n B) = n(A) + n(B).

C. The statement is true.

OD. The statement is false. If ANB+ Ø, then n(A U B) = n(B) – n(A).

First decide whether or not the conditions are possible to meet. Select the correct choice below and fill in the answer box(es) within your choice.

A. The number of elements in regions I, II, III, IV, V, VI, VII, VIII are 0,0,0,0,0,0,0, respectively.

O B. It is impossible to meet the conditions because there are only elements in set A but there are elements in set A that are also in set B or C. A similar problem exists for set C. (Simplify your answers.)
