The finite population among the options given is:
b. The number of grains of sand in a 10 lb bag of sandbox sand.
Explanation:
1. A finite population refers to a countable or limited number of items within a specific group.
2. In this case, the number of grains of sand in a 10 lb bag is limited and countable, making it a finite population.
3. Unlike continuous or uncountable populations like the number of light bulbs produced in a factory, the number of grains of sand in a bag is a fixed quantity.
Therefore, option b, the number of grains of sand in a 10 lb bag of sandbox sand, is the finite population among the choices provided.
