Question

Suppose "x<4" is false. Write a valid conclusion.

Answer 1

If x is less than 4 is false it means x is greater than or equal to 4.

Answer 2

Opposite of "less than 4" is "greater than or equal to 4"
So "x is less than 4" is false implies "x is greater than or equal to 4" is true.

Answer 3

Answer 4

correct.
