In a set of \( 100 \) items, \( 15 \) are defective. We pick randomly \( 10 \) items from this set. First eight items were not defective. Find the probability that the ninth item selected is not defective too. Results are rounded to two decimal places.
\( \frac{77}{92}=0{.}84 \)
\( \frac{85}{92}=0{.}92\)
\( \frac{15}{92}=0{.}16 \)
\( \frac7{92}=0{.}08 \)
