Name: _____________________________________________________ Date: ______________ 2. What is the theoretical probability of each colour on the map? P(yellow) = 100 P(white) = 100 P(brown) = 100 3. What is the theoretical probability of choosing each zone in the grid? P(Zone 1) = 100 P(Zone 2) = 100 P(Zone 3) = 100 P(Zone 4) = 100 4. You only have time to search 2 zones for the treasure. Which 2 zones will you search? Explain why you chose each zone. Zone Which zones will let you cover the most ground? ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ Zone ___________________________________________________________________________ ___________________________________________________________________________ ___________________________________________________________________________ 5.
