Correct Answer: D) legal environment

Explanation

The correct answer is option D: legal environment.

Unregistered patent medicine stores are being closed because they are operating illegally. In many countries, including Nigeria where this question is from, it is a requirement for patent medicine stores to be registered and licensed in order to ensure the safety and quality of the medicines being sold.

The legal environment refers to the laws and regulations that govern business activities. Closing unregistered patent medicine stores is a way to enforce these laws and protect the public from the potential dangers of unregulated medicines.

By closing these stores, authorities can ensure that only registered and licensed stores are allowed to operate, which helps to maintain the quality and safety standards of the medicines being sold. It also helps to prevent the sale of counterfeit or substandard drugs, which can have serious health consequences for consumers.

In summary, the closure of unregistered patent medicine stores is geared towards maintaining a legal environment where only licensed and regulated stores can operate, ensuring the safety and quality of medicines being sold.

Explanation

\(p(M) = 0.9 = \frac{9}{10} ; p(M') = 0.1 = \frac{1}{10}\)

\(p(P) = 0.75 = \frac{3}{4} ; p(P') = 0.25 = \frac{1}{4}\)

\(p(B) = 0.8 = \frac{4}{5} ; p(B') = 0.2 = \frac{1}{5} \)

p(at least two subjects) = p(Maths and Physics not Biology) or p(Maths and Biology not Physics) or p(Physics and Biology not Maths) or p(all three subjects)

= \((\frac{9}{10} \times \frac{3}{4} \times \frac{1}{5}) + (\frac{9}{10} \times \frac{4}{5} \times \frac{1}{4}) + (\frac{3}{4} \times \frac{4}{5} \times \frac{1}{10}) + (\frac{9}{10} \times \frac{3}{4} \times \frac{4}{5})\)

= \(\frac{27}{200} + \frac{36}{200} + \frac{12}{200} + \frac{108}{200}\)

= \(\frac{183}{200}\)

= \(0.915\)
