worst case
--------------
even distribution of 27 students' birth months across 12 months..
after 24 students, each month will have 2 students' birthday. The rest 3 students' birthday can go in to any month
making the count to 3 or more.

So this is always true or the situtaion will exists all the time and hence the probability should be 1 (E)
