Step-by-step explanation:

The two basic invalid mixed hypothetical syllogisms are:

1. If A then B. Not B. Therefore, not A.
2. If A then B. Not A. Therefore, not B.

In the first invalid syllogism, the conclusion states that A is false, when it is possible for B to be false even if A is true. In the second invalid syllogism, the conclusion states that B is false, when it is possible for A to be false even if B is true.
