Explanation:
6 boys * 6 girls
Total no of committees = 2(12}
No of committees (g) = 2(6) (boys)
No of committees (c2) = 2(6) (girls)
Total no committees = 2(6) + 2(6) =2(7)
Required no of committee when = (2(7) -1) ways
Committee = [2(12) – (2(7)-1)]
No of committees = 6 c1* 6c1 = 6*6 = 36
No of committees of at least 3 members = (212-27 +1) – [36]
=212-27 +1 –36
=212-27 -35
=4096-128-35
Total no of committees that can be formed = 3933
