Q10: Two male students and two female students
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 () be the cumulative distribution function of X and f(z) be the
probability mass function of X. Which one of the following statements is incorrect?
O F(2) > 0 when z- 0
O S(e) -0 when z =3
O fle) > 0 when z -0
OF (2) – 0 when z-3
O S(=)- P() when a<0
