Question

A survey of 300 girls of a school was conducted and it was found that 120 girls like mango while the rest dislike it. Out of these girls, one girl is selected at random. The probability that the selected girl does not like mango is

• A. $\frac{7}{15}$
  
• B. $\frac{2}{5}$
  
• C. $\frac{3}{5}$
  
• D. $\frac{1}{2}$
  

Answer 1

The correct option is C $\frac{3}{5}$


Total number of girls = 300
Number of girls who like mango = 120
Number of girls who dislike mango = $300–120=180$
$\therefore \text{P(selected girl does not like mango)}=\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$
$=\frac{180}{300}$
$=\frac{3}{5}$
Hence, the correct answer is option (c).
