Suppose, you are trying to pass a test for your driving license and once you pass, you don’t take the test again. The probability that it’d take you at most 6 attempts to pass the test for once is⁷²⁸⁄₇₂₉. What is the probability that it’d take you more than 3 attempts to pass the test for once considering the fact that you are allowed to make infinitely many attempts ?
