Problem 1. Let's suppose that our class has exactly 200 students. 1. There is an urn at the front of the classroom full of yellow, red, and green balls. Each student comes up and 6 times draws a ball and puts it back, and then writes down how many each of yellow, red, and green balls they drew. Show that there must be at least 8 students in the class who drew exactly the same number of yellow, red, and green balls. 2. Now suppose instead of drawing balls, each student writes down a string of length 6 in the alphabet {A, B, C}. How many students must be there be in the class to be guaranteed that at least two students write down the same string?
