At least one person from each gender?
Explanation:
Total number of ways of selecting one person from each gender = Total ways – Ways of selecting only women – Ways of selecting only men.
Total number of ways of selecting only women = 0
Total number of ways of selecting only men = 7C7 = 1
∴ Total number of ways of selecting one person from each gender = 1716 – 0 – 1 = 1715.
Hence, 1715.
