In his book, How to Solve it, G Polya gives four steps to problem solving 1. Understanding the prob 2. Devising a plan 3. Carrying out the plan 4. Looking back In devising a plan one of the strategies is to make a chart, as table, or a model of the problem For problem #14, choosing 2 bicycles, we could use a table like the following where the rows represent the first bicycle chosen and the columns represent the second bike chosen. Second bike chosen Black Green Red First bike Black x X chosen Green X Red x Critical thinking 1. How many difference selections could you make? 2. Why is row 1 column 1 (Black, Black) not x-ed? 3. If the order of selection is not important, is now 1 column 2 the same as row 2 column 1? 4. What other selections are equivalent if order is not important? 5. How many permutations are there-P(3.2? 8 How many combinations (sets) are there C13.27 Another way to organize your information is with a tree. The possible selection of a bike could be represented with the following tree diagram where B is for a black bike for green and R for red # page S How many possible chodes are there for the first official cold selected? How many forecord hp
