One coin in a collection of 5 is rigged to have a probability of showing heads equal to 0.2. The rest are fair (probability 0.5). A coin is chosen at random from the lot and tossed 3 times. It turns up heads 3 times in a row. What is the probability that it is the rigged coin given that it showed heads in 3 out of 3 tosses?
