IN THIS LESSON

Count the range before you take the risk.

Ivy and Shield compare a lemonade stand, a fixed car-washing payment, and a dog-walking offer. The same idea can produce different outcomes when weather, customers, or costs change. The lesson separates sales from what remains after costs and asks what you could lose—not just what you hope to earn.

The baskets-and-wagon example shows why spreading risk can help, and why a shared problem can still affect everything. The four-try probability example is an illustration with stated assumptions, not a promise of profit or a rule that smaller attempts always win.

TRY IT: Choose one small household or business decision with an uncertain outcome. Write the best case, worst case, and cost of trying. Ask whether you could handle the worst case and still meet essential commitments. What could you learn from a smaller, affordable test before making a larger commitment?

EXISTING PDF: The download explores additional insurance and investing examples through classroom-style activities. Those examples extend the topic; they are not the lemonade and dog-walking calculations shown in this revised film.
