Colored balls Memes

The eternal trauma of probability problems! What toddlers see as a fun game of "pick the pretty ball," combinatorics students recognize as the harbinger of mathematical doom. That innocent urn might as well be labeled "career-ending nightmare container." Those colored balls represent hours of calculating permutations, combinations, and probability distributions that will leave you looking like you've aged 50 years overnight. The difference between "How many ways can I grab a red ball?" and "Calculate the probability of selecting exactly k red balls in n trials without replacement, given hypergeometric distribution conditions" is basically the difference between joy and existential crisis.
