Anthony and Michael sit on the six-member board of directors for company X. If the board is to be split up into 2 three-person subcommittees, what percent of all the possible subcommittees that include Michael also include Anthony?

is it 20%
2 committees of 3 each can be formed in 6c3 = 20ways
Anthony and Michael both in one committee, take them as one object =4c1=4ways
now % = 4*100/20 = 20%
