Cory is a birdwatcher. 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,

63777 71890 01595 90500 43938
91971 58647 39440 28893 51995
What is the probability that at least one of the next five birds he sees is a
song sparrow?
