3 or less than 3 tires among the 10 tires should be blemished.
There are some possibilities.
1000 tires are blemished, (5000 - 1000) = 4000 tires are not blemished.
From the 5000 tires, 10 tires can be chosen in ways.
Possibility 1: <u>3 tires are blemished.</u>
Total 10 tires can be chosen with 3 blemished tires in ways.
Possibility 2: <u>2 tires are blemished.</u>
Total 10 tires can be chosen with 2 blemished tires in ways.
Possibility 3: <u>1 tires are blemished.</u>
Total 10 tires can be chosen with 1 blemished tires in ways.
Possibility 4: <u>No tires are blemished.</u>
Total 10 tires can be chosen with no blemished tires in ways.
Hence, the required probability is .
