From (5) men and (5) women, (3) persons are to be selected with at least (1) woman. How many ways are there?
Explanation opens after your attempt
C. (110)
Concept
Total ways are \(\binom{10}{3}=120\), and all-men selections are \(\binom{5}{3}=10\). Hence (120-10=110) ways.
Why this answer is correct
The correct answer is C. (110). Total ways are \(\binom{10}{3}=120\), and all-men selections are \(\binom{5}{3}=10\). Hence (120-10=110) ways.
Exam Tip
कुल \(\binom{10}{3}=120\) और केवल पुरुष \(\binom{5}{3}=10\) हैं। इसलिए (120-10=110) तरीके हैं।
