Answer: 93.3%
Explanation:
The labor force participation rate is the labor force of a country divided by its total adult population.
The labor force is defined as those working or actively looking for work.
Labor force participation rate = (Employed + Unemployed) / Employed + Unemployed + Discouraged + others not seeking employment)
= (25,000,000 + 3,000,000) / (25,000,000 + 3,000,000 + 1,000,000 + 1,000,000)
= 93.3%
