Question

In a school of 1900 students, there are 800 girls. Find the probability that a student chosen at random is a boy.

• A. $\frac{8}{19}$
• B. $\frac{11}{27}$
• C. $\frac{11}{8}$
• D. $\frac{11}{19}$

Answer 1

The correct option is D $\frac{11}{19}$

The number of students in a school = 1900.

Number of girls in a school = 800

Number of boys in a school =1900-800= 1100
​
Probability of choosing a boy = $\frac{\text{Number of boys in a school}}{\text{Number of students in a school}}$

$=\frac{11}{19}$
