Alfred Wegener has spent lot of times looking at maps, as it was his job. One day he noticed something peculiar, the western coast of Africa and the eastern coast of South America were an almost perfect match. They looked like peaces of puzzle that belong together. In his mind this was suggesting that these two continents had been merged in the past, and than broke apart. He later got proof about his theory by observing the sea mounts in the Atlantic Ocean.
They move by osmosis(a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.).
Total number of different committees = C(14,6) = N
We have two cases where we have less than 2 teachers.
case 1: 1 teacher (out of 5)
Number of ways to choose 1 teacher = C(5,1) = 5
Number of ways to choose the remaining members from students = C(9,5)
Total number of ways to choose a committee with exactly 1 teacher = 5C(9,5) = N1
case 2: no teacher
Number of ways to choose 6 students = C(9,6) = N2
Probability to choose at least two teachers
= (N-N1-N2)/N
=109/143
