**(+947)** . . 2002 AMC 12A Problems/Problem 16 (→Solution 3: existing solution 3 does not justify the symmetry, and we can't say in general that just because E(Tina's sum) = 6, we can just look for the probability that Sergio's # is >6.) - 17:08, 22 November 2019 (diff | hist) . . (+56) . . 2019 AMC 8 Problems/Problem 20 (condense solutions 1 and 2 to a more complete solution. Simply stating that the equation is quartic is not sufficient to show there are 4 real solutions.)
