6 engineering students want to take a P/NP of a course. The group includes 4 civil engineering students and 2 mechanical engineering students. Once the student is picked, they are not picked again. Let X be the number of turns until and including the first time a mechanical engineering student is chosen. What is the probability of X=2? Clearly explain your reasoning below. You may represent the intersection of 2 events A and B by AB, so you write (A intersect B) as P(AB).
