looked good to me

you can use $\frac{17}{100}\times \frac{16}{99}\times \frac{15}{98}$ or $\frac{\binom{17}{3}}{\binom{100}{3}}$ you will get the same answer

first method is quicker second method generalizes better for example 2, female, one male $\frac{\binom{17}{2}\binom{83}{1}}{\binom{100}{3}}$
