subject

Graduate students in cu’s little-known parapsychology department are conducting an experiment to test for extra-sensory perception (esp) in cu’s undergraduate population. their experiment involves showing a test-subject the back of a card with one of four shapes on the front side and asking them to correctly guess the shape. they perform this test on each test-subject 5 times. the study’s designers know from experience that a normal person without esp will correctly guess the shape on the card with probability 1/4. on the other hand, a person with esp will guess the correct shape with probability 7/8 (cosmic static sometimes gunks up the works, so even people with esp don’t guess the correct card every time). the designers also know that, at cu, 1 out of every 10 students has esp. you should input any numerical answers in decimal form, rounded to the nearest thousandth. for example, if you find 0.0148 as an answer, you should enter "0.015" a. if a test-subject does not have esp, what is the probability that they correctly guess all 5 cards that they are shown? answer b. if a test-subject in fact has esp, then what is the probability that they correctly guess 4 out of the 5 cards that they are shown? answer c. what is the probability that any test-subject (whose esp-status is unknown) correctly guesses all 5 cards that they are shown? (hint: use the law of total probability.)answer d. suppose that a test-subject (whose esp-status is unknown) correctly guesses all 5 cards that they are shown. what is the probability that the test subject has esp?
