Suppose there are 21 students in your class. If the teacher draws 2 names at random, what is the probability that you and your best friend will be chosen. The options are 2/21, 1/20, 1/105 and 1/210
Well, I want to say 2/21 but 1/210 would be better to go with. Even though 2/21 could be the correct answer because there are 21 students and the teacher is picking 2 random students, I'm going to have to go with 1/210.
