The correct answers are:

#3) If a person is not a musician, then the person is not a banjo player.

#4) Z is the inverse of X.

Explanation:

The contrapositive of a statement is formed by switching the hypothesis and the conclusion of a statement, and then negating both.

The hypothesis of a statement comes after "if," and the conclusion comes after "then." The hypothesis of our statement is "a person is a banjo player" and the conclusion is "the person is a musician." Switching these makes "If a person is a musician, then the person is a banjo player." Negating each of them makes "If a person is not a musician, then the person is not a banjo player."

#4) The two pieces of the statement, hypothesis and conclusion, are in the same position, but both are negated. The inverse is formed by negating both the hypothesis and the conclusion.
