For example, the first premise in the argument in Part B translates to: Anyone who is accepted at UP and wins the Lotto is happy.
Disprove the statement by giving counterexamples If m,n ∈ R, then |m + n| = |m| + |n|.
Let the universe of discourse be NBA players (active and retired), C(x) mean "x has won an NBA championship", "T(xy) means "x is the same height as or taller than y", and k = Kareem Abdul-Jabbar. Consider the following two statements: Væ[C(x) → -T(x, k)] -3z[T(x, k) A C(x)]. The second statement claims Kareem is the tallest player to win an NBA championship, but the first does not. These equivalent statements both say Kareem is the tallest person to win the NBA championship. These equivalent statements say Kareem is taller than anyone who won the NBA Championship, but they don't say anything about whether Kareem won. The first statement claims Kareem is the tallest to win the NBA championship, but the second does not.
(1) Indicate whether each statement is True (T) or False (F). If the statement is False, write its negation in simplified form: (a) Vx E R, if x =-1, then x=-I (b) 3x €Za vy e Z, (x+y)=x+y (c) Vm, Vn e Z, if m+n is even, then m is even and n is even
