Consider a randomly selected group of 100 students. Suppose 40 students major in Mathematics, 10 students major in Mathematics and Engineering, and 50 students are from other majors. If a student is selected randomly, what is the probability that the student is a) a Mathematics major but not an Engineering major, and b) either a Mathematics or Engineering major?
