The Sock in the Sock Drawer Part 2

The Sock in the Sock Drawer Part 2 extends the Grade 7 probability work to changing sample spaces. Groups select a sock color card, remove that outcome from the original set, and recalculate the probabilities for the remaining 18 socks. The activity makes it visible that probabilities change when an item is removed without replacement.

Use it after students understand the original sock-drawer sample space and are ready for dependent probability. Checking that the new probabilities still sum to 1 provides a useful built-in verification step. Create a free Find a Math Game account to generate teacher-ready lesson support for Part 2.
