There are two male students and two female students in a classroom. We randomly select two students from this classroom without replacement. Let X be the number of male students among the two selected students. Let F (2) be the cumulative distribution function of X and f (2) be the probability mass function of X. Which one of the following statements is incorrect? O F(2) > 0 when z = 0 O f(e) - 0 when z = 3 O f(2) > 0 when z -0 O F(2) - 0 when z = 3 O (r) - F (2) when a <0
