A 7 member committee is to be formed out of 8 boys & 5 girls. What is the probability that the
committee will have at least 2 girls?
• Total number of possibilities:
• 13C 7 = (13*12*11*10*9*8)/(6*5*4*3*2)
• =1716
• Favourable possibilities:
• 2 girls + 5 boys: (8c5 *5c2) =56*10

• Favourable possibilities:
• 4 boys+ 3 girls =: (8c4 *5c3) =70*10
• 3 boys+ 4 girls =: (8c3 *5c4) =56*5
• 2 boys+ 5 girls =: (8c2 *5c5) =28*1
• =560+700+280+28 =1568
• Thus required probability is 1568 / 1716

• 2 persons before 5 and 1 person after 7 =24 = =3*8 = 24 alternatively 3c2 *8C1 = 24
• 1 person before 5 and 2 persons after 7=84 = (4c1 * 7c2) = 4*21 = 84
• 3 persons after 7 = (8-3+1) C3 = 20
• Add them together = 128 answer.
