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.
What is the probability that there are less than 5 members in a typical household in India? (Round your answer to 2 decimal places.)
What is the probability that there are 5 or more members in a typical household in India? (Round your answer to 2 decimal places.)
What is the probability that the number of members in a typical household in India is greater than 2 and less than 5 members? (Round your answer to 2 decimal places.)

Solution
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.
What is the probability that there are less than 5 members in a typical household in India? (Round your answer to 2 decimal places.)
Less than 5 means household size is either 1 or 2 or 3 or 4.
Probability(Less than 5=P(1)+P(2)+P(3)+P(4)=0.03+0.09+0.17+0.21=
What is the probability that there are 5 or more members in a typical household in India? (Round your answer to 2 decimal places.)
5 or more means household size is either 5 or 6 or 7 or 8.
What is the probability that the number of members in a typical household in India is greater than 2 and less than 5 members? (Round your answer to 2 decimal places.)
greater than 2 and less than 5 members means household size is either 3 or 4.
