In France, the consumption of organic products has been growing for several years.
In 2017, the country had $52\%$ women. That same year, $92\%$ of French people had already consumed organic products. Furthermore, among consumers of organic products, $55\%$ were women.
We randomly choose a person from the file of French people in 2017. We denote:
  • $F$ the event ``the chosen person is a woman'';
  • $H$ the event ``the chosen person is a man'';
  • $B$ the event ``the chosen person has already consumed organic products''.

  1. Translate the numerical data from the statement using events $F$ and $B$.
  2. a. Show that $P(F \cap B) = 0{,}506$. b. Deduce the probability that a person consumed organic products in 2017, given that they are a woman.
  3. Calculate $P_H(\bar{B})$. Interpret this result in the context of the exercise.
