India is the second most populous country

India is the second most populous country in the world, with a population of over 1 billion people. Although the government has offered various incentives for population control, some argue that the birth rate, especially in rural India, is still too high to be sustainable. A demographer assumes the following probability distribution of the household size in India.

1 0.05
2 0.09
3 0.12
4 0.24
5 0.25
6 0.12
7 0.07
8 0.06
