Final answer:
The conditions listed in the question determine filing as a dependent for tax purposes, not Medicaid eligibility. Medicaid provides insurance to low-income individuals including families with children, the elderly, and disabled.
Step-by-step explanation:
The conditions you're referring to, specifically being under age 19 at the end of the year, under age 24 at the end of the year and a full-time student, or permanently and totally disabled, are criteria that determine filing as a dependent for tax purposes.
These are not the qualifications for Medicaid eligibility. Medicaid is a federal-state joint program that provides medical insurance for low-income individuals, including families with children, the elderly, and people with disabilities. However, the age criteria and full-time student status mentioned are not included in the Medicaid eligibility requirements.
