    Permutation is used to arrange the object and combination is used firstly to select and then arrange

    Permutation is generally used at the places where we have to take the number of observation only ones where as in combination we can use a number of observation on the given set twice or the way we want. For example if I have to make a car from using red paint green paint and blue paint then I have to use permutation because I have to use only one colour out of all where is in combination if I have to make a team of 2 girls and 2 boys from 7 boys and 7 girls they can be any it doesn't matter on the boy or girl so here we use combination rather permutation.
