a. The probability that all 4 members on the committee will be girls is (Type an integer or a simplified fraction.)

To calculate the probability that all 4 members on the committee will be girls, we need to know the total number of members available and how many of them are girls. Let's denote: - \( G \): the number of girls - \( T \): the total number of members The probability \( P \) that all 4 members selected are girls can be calculated using the formula: \[ P = \frac{\text{Number of ways to choose 4 girls}}{\text{Total number of ways to choose 4 members}} \] The number of ways to choose 4 girls from \( G \) girls is given by the combination formula: \[ \binom{G}{4} = \frac{G!}{4!(G-4)!} \] The total number of ways to choose 4 members from \( T \) total members is: \[ \binom{T}{4} = \frac{T!}{4!(T-4)!} \] Thus, the probability can be expressed as: \[ P = \frac{\binom{G}{4}}{\binom{T}{4}} = \frac{\frac{G!}{4!(G-4)!}}{\frac{T!}{4!(T-4)!}} = \frac{G! \cdot (T-4)!}{T! \cdot (G-4)!} \] To provide a specific answer, I need the values of \( G \) and \( T \). Please provide those numbers.
