Your solutions should be clear, complete, and sufficiently detailed in order to demonstrate your understanding and communicate your reasoning and method of solving the problem. Exercise 1 A psychologist has conducted a series of experiments to scientifically study the phenomenon known as extrasensory perception (or ESP). In one experiment, a test subject is brought into a room and seated in a chair facing a blank wall. The experimenter stands behind the seated test subject and randomly selects one of the following five cards. C The experimenter then asks the test subject to identify the symbol on the randomly selected card. The test subject's response is recorded along with the symbol on the randomly selected card. Before the test subject gives their consent to taking part in the experiment, the experimenter explains the process of the experiment and shows the symbols on the cards to the test subject. If the test subject does not possess the power of ESP and is merely guessing the symbol of the randomly selected card, what is the probability that the test subject will correctly identify the symbol?
