If you are an alien then you are green. Rewrite the statement in “if…then...” form and identify the hypothesis and conclusion. All aliens are green. If you are an alien then you are green. hypothesis conclusion

Which of the following choice(s) is/are the symbolic form of the given conditional statement? If a Number is greater than zero, then it is Postive. N  P P  N P  N N  P N  P P  N

If t is a true statement and f is a false statement, which of the following conditional(s) is/are true? 1. t  f 5. t  ~f 2. f  t 6. f  ~t 3. ~t  f 7. ~t  ~f ~f  t 8. ~f  ~t

Which pair(s) of statements can be rewritten as one biconditional? Conditional #1: If I am hungry then I will eat dinner. Conditional #2: I will eat dinner if I am hungry. Conditional #3: If I eat dinner then I will eat dessert. Conditional #4: If I eat dinner then I am hungry.

Which pair(s) of statements can be rewritten as one biconditional? Conditional #1: If I am hungry then I will eat dinner. Conditional #2: I will eat dinner if I am hungry. Conditional #3: If I eat dinner then I will eat dessert. Conditional #4: If I eat dinner then I am hungry.

Rewrite the biconditional as a pair of conditional statements. I am happy if and only if I am in Geometry. If I am happy then I am in Geometry. If I am in Geometry then I am happy.
