Answer:
Total number of committee which can be formed from 10 people(6boys and 4 girls) = 10C5=252
When number of girls in a committee is exactly 2, means no. of boys in committee should be 3.
So number of combinations having 2 girls and 3 boys in committe = (6C3)*(4C2)=120
So probability= 120/252=10/21=.4761=47.61%
