    ok, this is a permutation, because the order of the items matters the formula for permutations is nPr = n!/(n-r)!, where n is the number of total items and r is the number of items you are picking at once so, n = 10 jars, because there are 10 total jars, and r = 6, because we are only putting 6 on the shelf at once
