Answer:

5/33649= approx 0.00015

Step-by-step explanation:

Total number of outcomes are C24 6= 24!/(24-6)!/6!=19*20*21*22*23*24/(2*3*4*5*6)= 19*14*22*23

Half of the Committee =3 persons. That mens that number of the women in Commettee=3. 3 women from 6 can be elected C6 3 ways ( outputs)=

6!/3!/3!=4*5*6*/2/3=20

So the probability that 3 members of the commettee are women is

P(women=3)= 20/(19*14*22*23)=5/(77*19*23)=5/33649=approx 0.00015
