12. Witney Pete, a professional dart player, has a 70% chance of hitting the bull's eye on a dartboard with any throw. Assume that each throw of a dart is independent. a. Suppose Pete throws darts until he hits his first bull's eye. Find the probability that his first bull's eye occurs on the third throw. b. What is the probability that Pete hits 5 or fewer of his next 10 shots? c. Pete forgets his eyeglasses one evening, but he's confident he's just as accurate without them. On his first 10 shots of the night, he hits the bull's eye only 5 times. Is this evidence that his glasses are important? Explain
