At a fund-raiser, students pay $5 for the chance to throw a pie in the faces of their teachers. The student flips a coin twice. If the results are the same both times (two heads or two tails), the student's chosen teacher flips the same coin three times. If the teacher does not get the same results all three times, the student gets to hit the teacher in the face with a pie. However, if the student does not get the same results on both of his flips, and the teacher does get the same results on his three flips (three heads or three tails), the teacher gets to hit the student with a pie.
1) Calculate the probability that the student gets to hit the teacher.
