Who knows 3 examples of priori knowledge and Empirical knowledge?

Priori knowledge examples: Posteriori examples:

1. today is Thursday It is snowing outside

2. all boys are males The fruit is an Apple

3. all bachelors are unmarried The wood is rough and hard

the only priori knowledge I am aware of are mathmetical truths such as 2 +2 = 4 because they are true without expirimentation or observation.
