In the classes that I teach, one class period is devoted to a procedure called Q-sorting. I won't bore you with the details. What's important here is that you know that students fill out a questionnaire and enter data into a computer program. The program then tells them how compatible they are (in terms of likes, dislikes, and interests) with everyone else in the class. It's a lot like what dating websites do.

Anywho, one of the activities during this period is for each student to find the classmate with whom the computer says he/she is most compatible, talk to that person, and decide whether the computer made an accurate assessment. Two of my students told me after class today that the computer had matched them as highly compatible. After talking, they realized that they had previously met on the internet (6 years ago), HAD BEEN 'FRIENDS' FOR YEARS but had never previously talked outside of a computer chat room (they had never even seen each other), and they DIDN'T KNOW THEY WERE IN THE SAME CLASS UNTIL THE COMPUTER TOLD THEM SO.

What are the chances of that?
