Keshawn has 19 other potential partners with equal probablility of each. (That is because there is a total of 20 students). What does that tell you?
he has a probability of 1:19?
is 1:19 the correct answer? Because, the more I think about it, the more confused I get since there are 20 students in the class, but it has to be 19, since Keshawn can't be partnered with himself, right?
