It seems like there might be some missing information in your question. To calculate the probability that all 4 members on a committee will be girls, we typically need the following details:

1. **Total number of girls available** (let's denote this as $$ G $$).
2. **Total number of students available** (both girls and boys, denoted as $$ N $$).
3. **Size of the committee** (which you've specified as 4 members).

The probability $$ P $$ that all 4 members selected are girls can be calculated using the combination formula:

$$
P = \frac{\binom{G}{4}}{\binom{N}{4}}
$$

Where:
- $$ \binom{G}{4} $$ is the number of ways to choose 4 girls out of $$ G $$ girls.
- $$ \binom{N}{4} $$ is the total number of ways to choose any 4 students out of $$ N $$ students.

**Example:**
If there are 10 girls and 20 students in total, the probability would be:

$$
P = \frac{\binom{10}{4}}{\binom{20}{4}} = \frac{210}{4845} = \frac{42}{969} = \frac{14}{323}
$$

Please provide the total number of girls and the total number of students so I can help you calculate the exact probability.
To find the probability that all 4 committee members are girls, you need to know the total number of girls and the total number of students. Once you have those numbers, use the combination formula: $$ P = \frac{\text{Number of ways to choose 4 girls}}{\text{Total number of ways to choose 4 students}} $$ For example, if there are 10 girls and 20 students: $$ P = \frac{\binom{10}{4}}{\binom{20}{4}} = \frac{210}{4845} = \frac{14}{323} $$ Please provide the specific numbers to get the exact probability.
