Conditional probabilityMathematics can often be seen as a daunting subject, full of complex formulas and equations. Many students find themselves struggling to solve math problems and feeling overwhelmed by the challenges they face.To find mean, we add up the values in a set and divide by the number of terms in that set. We begin this problem with the knowledge that the mean of the first set is 20. Since that set contains five numbers, we know that its total sum must be 100 (since 100 divided by 5 is 20). so must be 25. Now, the only step left is to find the mean of .Consider statistics as a problem-solving process and examine its four components: asking questions, collecting appropriate data, analyzing the data, and interpreting the results.
