Final answer:
The question relates to a mathematical problem about ratios and probabilities but lacks sufficient detail to directly answer it. Relevant discussions may involve computing averages, probabilities, and understanding statistical distributions.
Step-by-step explanation:
The student's question appears to be part of a mathematics problem concerning ratios and probabilities. Unfortunately, the details provided are insufficient to give an accurate answer to the initial ratio question regarding the number of words typed by Ima Smurf in 3 minutes. However, related information suggests this is part of statistical calculations - potentially involving the mean, percentiles, sample averages, or a discussion of probability distributions (e.g., normal vs. exponential distributions).
Solution strategies for the parts of the question with sufficient information might include computing averages and probabilities, understanding complements in probability, and interpreting percentile information. Compatibility with a particular probability distribution could involve checking the given data against the characteristics that define exponential and other distributions.
