text: ## Elementary Statistics (12th Edition)
  
  a)We know that $probability=\frac{number \ of \ good \ outcomes}{number\ of\ all\ outcomes}$, hence $P(Fraternal \ twins)=\frac{5+5+5+5}{5+0+0+5+5+5+5+5}=0.666.$ b)We know that $probability=\frac{number \ of \ good \ outcomes}{number\ of\ all\ outcomes}$, hence $P(Fraternal \ twins|Boy \ and \ Girl)=\frac{5+5}{0+0+5+5}=1.$
explanation: The text extract is from an elementary statistics textbook and contains two parts, each presenting a probability calculation. Each part includes a formula for calculating probability and applies it to a specific scenario involving fraternal twins. The extract provides both the questions and the answers for these probability problems.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
