Suppose a coin is flipped 3 times and the sequence of H/T recorded. Let A be the event that the first flip is heads, and let B be the event that exactly 2 heads are flipped. Show that P(A|B) ̸= P(B|A) by computing both P(A|B) and P(B|A) directly. You can assume all sequences of H/T are equally likely.
