The probability of successfully landing a plane using a flight simulator is p. nine randomly and independently chosen student pilots were asked to try to fly the plane using the simulator. let x be the number of student pilots among these nine who land the plane successfully. what is the probability that at least one of the student pilots will successfully land the plane using the simulator? since the probability of landing successfully, p is unsolvable numerically. i left my answer in terms of p. let success = p and fail = 1 - p. what i wanted to know, is my answer correct in the approach i took, using binomial distribution? my answer is attached below as a picture, for formatting purposes.
