Unformatted text preview: (10,5)". There is many ways the same answer might be given. In this example the same answer can be given as P(10,3)/P(3) + P(10,5)/P(5), or as 10!/(7!*3!) + 10!/(5!*5!). But we don't want you to simplify these and rewrite them as: 8*9*10/2*3 + 6*7*8*9*10/1*2*3*4*5, or even worse, cancelling these out and giving us an answer as 4*3*10 + 7*2*9*2 etc. All these formulas are express the same thing so numerically they are equivalent, but as in the previous homework the are two points: First, from an answer of the last type it's very hard for the grader to tell what's the logic that led you to giving this answer. Second, there's no point you should waste time computing these expressions numerically because this is not the point of these exercises. file:///C/Documents%20and%20Settings/Linda%20Grauer/M. ..ocuments/Dolores/UC%20IrvineHarvest/ICS%206D/hmw7.htm [1/30/2008 12:06:49 PM]...
