Best ResponseYou've already chosen the best response.1Suppose there is no chairperson and secretary. Now you have eight members. who can be arranged in 7! Now one among the pair of secretary and chairperson can be seated in 8 ways around the table ( the other will be just opposite). so, you have a total of 7! \(\times\) 8
