Given Probability Problem does not work if Greg's alternative approach is used

[wtftutor] For the Given Probability PrepSwift video, Greg demonstrates that in a “given” probability problem, you can use the probability OR the number of the permutations of cases. For example, for Case 3 and Case 4 of the screenshot, I should be able to calculate: Case 3: 4! / (2!)(2!) = 6 Case 4: 4! / 3! = 4 Case 5: 4! / 4! = 1 Then I put Case 5 / All → 1 / 11 This is not the right answer. Thus, the number of cases alternative approach should not be used? Please help! Update:…

"Given Probability" Problem

In the “Given Probability” video on PrepSwift, Greg does a problem two different ways. Way 1: [image] Way 2 [image] Then Greg does the following problem in way 2. [image] I tried to do this problem way 1. [image] Am I doing something wrong here? Why this discrepancy?
