El \( 25 \% \) de los habitantes de una villa de 200 personas son jubilados, otro \( 25 \% \) son estudiantes. Si al \( 80 \% \) de los jubilados, al \( 10 \% \) de los estudiantes y al \( 20 \% \) del resto de la población les gusta la música clásica, entonces, la probabilidad de que elegida una persona al azar le guste éste tipo de música es

Question 12 If \( P(A)=0.15, P(B)=0.2 \), and \( A \) and \( B \) are independent, Find \( P(A \) and \( B) \). Add your answer Integer, decimal, or E notation allowed

Two newspapers \( A \) and \( B \) are published in a city. It is known that \( 25 \% \) of the city populations reads \( A \) and \( 20 \% \) reads \( B \) while \( 8 \% \) reads both \( A \) and \( B \). Further, \( 30 \% \) of those who read \( A \) but not \( B \) look into advertisements and \( 40 \% \) of those who read \( B \) but not \( A \) also look into advertisements, while \( 50 \% \) of those who read both \( A \) and \( B \) look into advertisements. Then the percentage of the population who look into advertisement is [JEE (Main) 2019] \( \begin{array}{ll}\text { (a) } 12.8 & \text { (b) } 13.5 \\ \text { (c) } 13.9 & \text { (d) } 13\end{array} \)

If \( P(A)=0.25, P(B)=0.6 \), and \( P(A \) and \( B)=0.2 \), are \( A \) and \( B \) independent? A) No (B) Yes
