Cory is a bird-watcher. He estimates that 30% of the birds he sees are
American robins, 20% are dark-eyed juncos, and 20% are song sparrows. He
designs a simulation.
Let 0, 1, and 2 represent American robins.
Let 3 and 4 represent dark-eyed juncos
Let 5 and 6 represent song sparrows.
Let 7, 8, and 9 represent other birds.
The table shows the simulation results.
