Lena put on a blindfold and picked 47 jelly beans from a jar. Is this sample of the jelly beans in the jar likely to be representative? Choices: (A)yes (B)no

Understand representative sample: Understand the concept of a representative sample. A representative sample accurately reflects the distribution of characteristics in the entire population.Consider sample size: Consider the size of the sample relative to the total. If the jar contains a much larger number of jelly beans, 47 may not be enough to capture all variations, especially if the jelly beans are not uniformly mixed.Analyze selection method: Analyze the method of selection. Lena picked the jelly beans blindfolded, which suggests randomness in the selection process; however, without stirring or mixing, some types of jelly beans might be over or underrepresented.Make conclusion: Make a conclusion based on the analysis. Given the random selection, the sample might seem representative, but without knowing the total number or the mixing state of the jelly beans, it's risky to assume it's fully representative.
