Answer:
156 different pairs will be there.
Step-by-step explanation:
As the order is essential as we need different pairs therefore permutations will be used.
A permutation is any ordered subset of the objects r selected with regard to their order, from the set of n distinct objects. It is given by nPr where n> r
Total number is 13 and required number is 2
n= 13 and r= 2
13 P2= 156 possible combinations.
A combination is any subset of the objects r selected without regard to their order, from the set of n distinct objects. It is given by nCr where n> r
