Final answer:
Rounding off in mathematical problems, specifically in probability, requires maintaining the precision of the original data by rounding the final answer to one more decimal place than what was given.
Step-by-step explanation:
The question you've asked relates to rounding off numerical answers in probability problems and the importance of significant figures in reporting your results. When you round off a number in mathematics, especially in probabilities, it is crucial to maintain a certain degree of precision that correlates with the original data presented. Generally, you should report your final answer with only one more decimal place than the data you were working with to avoid excessive and misleading precision.
For example, with a data point measured to the nearest tenth, your final value should be rounded to the nearest hundredth. In problems where intermediate steps are involved, avoid rounding until the final answer, unless absolutely necessary. The instructions specific to your coursework indicate the number of decimal places to round to and stress the importance of understanding the level of precision required for various mathematical exercises.
