3 drawers labeled red/blue, blue/green, green/red. all labels are wrong. expected num of socks to draw to identify all 3? classic. start with red/blue drawer - since its mislabeled it must be green/green or blue/blue etc. actually only need to draw from one drawer to deduce all 3 (logic puzzle). but the EXPECTED number under random draws is different. they want the random expectation. ~3-ish socks i think? worked it out on paper. still rotating in 2025-26 reports
