SUMMARY
The discussion focuses on proving that the expression 20Cr × 0.1^r × 0.9^(20-r) achieves its maximum value when r equals 2. The user highlights the challenge of differentiating the expression due to the discrete nature of the binomial coefficient nCr. A solution to this problem is referenced from Math Stack Exchange, which provides a method for determining the maximum term in the binomial expansion.
