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 | 0.02 |
| 2 | 0.09 |
| 3 | 0.18 |
| 4 | 0.25 |
| 5 | 0.20 |
| 6 | 0.12 |
| 7 | 0.08 |
| 8 | 0.06 |
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 2 and 5?
(Round your answer to 2 decimal places.)

| Household Size | Probability |
| 1 | 0.02 |
| 2 | 0.09 |
| 3 | 0.18 |

a.
P(Less than 5 members in a household in India)
=P(Household size = 1) + P(Household size = 2)+P(Household size = 3)+P(Household size = 4)
b.
P(5 or more members in a household in India)
=P(Household size = 5)+P(Household size = 6) + P(Household size =7)+P(Household size = 8)
c.
P(the number of members in a household in India is strictly between 2 and 5)
= P(3) + P(4)
