Exercise 5-7 Algo
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 for the household size in India.
| Household Size | Probability |
| 1 | 0.04 |
| 2 | 0.10 |
| 3 | 0.18 |
| 4 | 0.24 |
| 5 | 0.19 |
| 6 | 0.15 |
| 7 | 0.07 |
| 8 | 0.03 |
a. What is the probability that there are less
than 5 members in a household in India? (Round your answer
to 2 decimal places.)
b. What is the probability that there are 5 or
more members in a household in India? (Round your answer to
2 decimal places.)
c. What is the probability that the number of
members in a household in India is strictly between 3 and 6?
(Round your answer to 2 decimal places.)

Indonesia is the fourth most populous country in the world. It is an island nation in southeast Asia. Half of the population lives on the largest island, Java, while the other half of the population is scattered among 13,000 smaller islands. Indonesia is a collection of several hundred unique ethnic/cultural groups, with each having their own language. Determine which population genetics term best describes each of the hypothetical scenarios below: 1) In 1883, more than two thirds of Krakatoa island...
