Your goal is to come up with two events A and B, where P(A|B) is high but P(B|A) is low of a real life example.

Example 1: My events are "You are dead" and "A shark has bitten your head off". Then P(you are dead | shark bit your head off) is high but P(shark bit your head off | you are dead) is low (because sharks rarely bite people's heads off)

Example 2: P(You eat something | You are hungry) is high but P(You are hungry | You eat something) is low since eating minimizes the feeling of hunger.
