Question

We are given three coins: one h heads in both faces, the second h tails in both faces, and the third h a head in one face and a tail in the other. we choose a coin at random, toss it, and the result is heads. what is the probability that the opposite face is tails

Answer 1

If the result is head and you want the other side to be tail, there is only 1 coin that can give this result. So the probably is 1/3
