In: Statistics and Probability
Here is a project I am currently working on and I could use some feedback on how to get started. I calculated the general probabilities for the first two columns of each spreadsheet (successes / total outcomes). I don't want to move forward until I know I'm on the right track but I'm concerned that I've oversimplified the question being asked. I'm also using Excel and am having a hard time finding an appropriate formula for conditional probability. My book provides the handwritten formula but not for Excel. Is there one? Thanks for any guidance!
-------------------------------------
The spreadsheet provides the data for the total cases disposed, numbers of appealed cases and the numbers of reversed cases for judges in each court. Using Excel, calculate the following probabilities for each judge. Use the spreadsheets to fill in these numbers on the tables for each court.
1. The probability of a case being appealed for each judge.
2. The probability of a case being reversed for each judge.
3. The probability of a reversal given an appeal for each judge.
