They are the prime ministers/presidents of the countries of Canada, China, France, Germany, India, Japan, Libya, Malaysia, Philippines, South Korea, USA, and United Kingdom. If the seating arrangement is to be circular, how many seating arrangements are possible?Create your own seat plan for these 12 leaders based on your knowledge of their backgrounds. Discuss why you arranged them that way.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
