♥ open question: combinations and permutations help?
♥ okay, so, i have a hard worksheet and i am having trouble wrapping my head around each problem. i am allowed to use a calculator, and it would help if you tell me what i should enter (like ncr or npr) given that 5 drivers stand in a line, the tallest driver stands in the center and the remaining drivers stand according to their heights from the tallest at the center to the shortest at each end. f no two drivers are the same height, how many different arrangements are possible? what i have: the tallest is in the center so theres only one option for that. the middle two heights have 2 options each, and the shorter 2 heights have 2 options each as well. but how would i figure out the answer? i have more of these, but im thinking just really understanding one will help me enough. thank.
