Hellppp lan often takes his dog to the park. He estimates that 30% of the other dogs
he sees are retrievers, 20% are terriers, and 20% are German shepherds. He
designs a simulation.
Let 0, 1, and 2 represent retrievers.
Let 3 and 4 represent terriers.
Let 5 and 6 represent German shepherds.
Let 7, 8, and 9 represent other dogs.
The table shows the simulation results.
