Kari started off the probability workshop with the classic coin flip example. She was trying to demonstrate that even though each side had a 50% chance of landing face up, it didn't necessarily mean that would be the case. It ended up being perfectly even, but the kids still got the idea. Ebonee stepped in and used the 'race car' activity for a more hands on example (shodor.org/interactivate/activities/race). She also segued into the burning forest applet, which is where Monte took charge (shodor.org/interactivate/activities/fire1/indexflash.html). He used this applet as well as the 'better fire' one to show some real-world applications of probability (a la firefighters).
Next came the MM activity, dealing with the same issues. Collectively, the workshop kids picked out a certain number of MM's, then combined the color data to make one big pie chart. The distribution among each color turned out to be pretty even.
