Beyond the Answer

To find the probability that none of the female undergraduates have taken on debt, we can use the complement of the probability that a female undergraduate takes on debt. Given that \( P(\text{debt}) = 0.43 \), the probability that a female undergraduate does not take on debt is \( P(\text{no debt}) = 1 - 0.43 = 0.57 \). Now, since we are selecting 9 female undergraduates, we can find the probability that all of them have not taken on debt. This is calculated as: \[ P(0 \text{ female undergraduates take on debt}) = (P(\text{no debt}))^n = (0.57)^9 \] Calculating this gives: \[ (0.57)^9 \approx 0.025 \] So, the probability that none of the female undergraduates take on debt is approximately **0.025** when rounded to three decimal places.
