Combination locks : I forgot the combination! How many combinations will I have to try?
This activity asks the student to find the number of possible combinations for a lock showing the numbers 0 to 39. It is part of the Figure This! collection of 80 online mathematical challenges emphasizing real world uses of mathematics. The solution to the combination question applies the technique of using a smaller number of possible arrangements to study a problem. Students learn to use a tree diagram to model possible outcomes and explore the mathematical meaning of the term combination. Th
