### Question 4

A class has 7 boys and 4 girls. What is the probability of choosing 1 boy and 2 girls?

**A**

${14/55}$.

**B**

$8/11$.

**Soln.**

**Ans: a**

Three students have to be picked. Total number of ways = ^{11}C_{3} = ${11 × 10 × 9}/{3 × 2 × 1} = $165. Number of ways of picking 1 boy and 2 girls = ^{7}C_{1} × ^{4}C_{2} = 42. So probability = $42/165$ = ${14/55}$.
