Answer:

never

Explanation:

The expression: ~q means "not q"

If ~q is false, then q is true

The expression:

If p is true and ~q is false

is equivalent to:

If p is true and q is true

then:

If p is true and q is true, then p -> q is never false (or is always true, see table attached). Or:

If p is true and ~q is false, then p -> ~q is never false.

If p is true and ~ q is false, then p ~ q is always, sometimes, never false.-example-1
