Show Hint
For probability problems involving selection without replacement, use the hypergeometric distribution formula to calculate the probabilities of selecting various numbers of a specific type of object.

- \( \frac{7}{5} \left( \frac{9}{10} \right)^4 \)
- \( \frac{7}{5} \left( \frac{9}{10} \right)^5 \)
- \( \frac{6}{5} \left( \frac{9}{10} \right)^4 \)
- \( \frac{6}{5} \left( \frac{9}{10} \right)^5 \)
