We are selecting 2 students at random (without replacement) from this group of 7 students. 5 (25 marks) assume the probability that a newborn is a boy is 50 %, that is, p = 0. 5. Suppose a family has 8 children. (a) what is the distribution law followed by the number of boys in such a family? (b) denote f the cumulative distribution function of this distribution law.
