What is the probability that the committe has at least 1 man or at least 1 women?

All male probability: 10/24*9/23*8/22*7/21 = 5040/255,024
= 0.01976
All female probability:
14/24*13/23*12/22*11/21= 24,024/255,024
= 0.09420
prob. of at least one man and one woman:
= 1  (prob. of zero males)  (prob. of zero females) = 1 0.01976  0.09420
