What are permutation and combination?
A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
Tim (T), Paco (P), Maria (M), and Jenny (J) are standing in line for lunch.
Jenny is standing between Paco and Maria.
Then the arrangement will be PJM or MJP.
Paco's position in line is an odd number. Then the order will be PJM or MJP
