### Question 2

There are 40 students in Class X of a school of whom 25 are girls and 15 are boys. If one student is absent today, what is the probability that it is a girl?

### Question 3

A class has 5 boys and 3 girls. What is the probability of choosing 1 boy and 2 girls?

**A**

${15/56}$.

**B**

$6/8$.

**C**

$16/56$.

**D**

$20/56$.

**Soln.**

**Ans: a**

Three students have to be picked. Total number of ways = ^{8}C_{3} = ${8 × 7 × 6}/{3 × 2 × 1} = $56. Number of ways of picking 1 boy and 2 girls = ^{5}C_{1} × ^{3}C_{2} = 15. So probability = $15/56$ = ${15/56}$.
