first a boy, take him out to the principal's office, then a girl?
m + 12 students
boy first
m/(m+12)
now we have (m-1)+12 students
pick a girl
12/(m+11)
so the product is
12m/[(m+12)(m+11)]
or
12m/(m^2 + 23m + 132)
m + 12 students
boy first
m/(m+12)
now we have (m-1)+12 students
pick a girl
12/(m+11)
so the product is
12m/[(m+12)(m+11)]
or
12m/(m^2 + 23m + 132)
