You have 8 marbles and a balance scale. One marble weighs more than the others, but you don’t know which one. How can you identify the heavier marble using only two weighs of the balance scale?

2 réponses

We put 3 marbles on each side of the scale for a total of 6 marbles that are being weighed. We leave 2 marbles off the scale. Then, we compare the 6 marbles… There are two possible outcomes: If one side is heavier than the other then we only have 3 marbles left. Then, in the second weighing, we can compare 2 of those 3 marbles to each other. If they are the same weight, then the 3rd is the heaviest. If one is heavier than the other, then we’ve succeeded in just two weighings. If, when comparing the 6 marbles, we find that both sides are equal, then we know that the heaviest marble has to be in the 2 marbles that are not on the scale. This means that we only have to compare on those 2 remaining marbles and we have the heaviest marble in only two weighings. Moins

From the question, I am assuming how would you validate data analysis. Here are my answers: I usually perform exploratory data analysis from the given data to uncover many insights. through data, I would like to understand descriptive statistics. Write a summary of all observations, correlations of all variables, anomalies found, assumptions made, etc. Once my report is complete I validate with the subject matter expert to have a discussion on what the data is telling us so far and see if there are any surprises or intersections between analysis and SME's Moins
