An online psychic (psi) ability or extrasensory perception (ESP) test shows the participant five face-down cards on the screen and asks the participant to "click on the one card that has a picture on the other side." After clicking a card, the test shows you the card to determine if your guess was correct. If a person does not have ESP, what is the probability the person's guess is correct? 0.10 0.80 0.50 0.20
