Out of 9 outstanding students in a college, there are 4 boys and 5 girls. A team of four students is to be selected for a quiz programme. Find the probability that two are boys and two are girls.

Explanation

To solve the problem of finding the probability that a team of four students consists of two boys and two girls from a group of 4 boys and 5 girls, we can follow these steps:

### Step 1: Determine the total number of ways to select 4 students from 9.
The total number of students is 9 (4 boys + 5 girls). We can calculate the total number of ways to choose 4 students from these 9 using the combination formula:

\[ \text{Total ways} = \binom{9}{4} \]
