Hi
In a class of 40 students, 14 of which are girls, 6 students are to be selected at random. 
 a. In how many ways can their teacher choose 6 students? 40C6= 3838380
 b. In how many ways can their teacher form a committee consisting of 3 girls and 3 boys? {{{(14C3)(26C3)}}}= 946,400 ways
 c. In how many ways can their teacher form a committee consisting of 2 girls?{{{(14C2)(26C4)}}}
 d. What is the probability that at least two girls are chosen
{{{(14C2)(26C4)/(40C6)}}} + {{{(14C3)(26C3)/(40C6)}}}+{{{(14C4)(26C2)/(40C6)}}}+{{{(14C5)(26C1)/(40C6)}}} + {{{(14C6)(26C0)/(40C6)}}}
