See figure attached below for the question.
I'm at a loss as to how they obtain an answer of C) for the solution. Can anyone explain this?
I was thinking of taking the odds of one underdog winning and or'ing it with the other chances of the other underdogs winning as such,
(0.43)(0.72)(0.89)(0.67)(0.82) + (0.57)(0.28)(0.89)(0.67)(0.82).... etc
Where the underdogs are in bold.
Can someone explain how to solve this question?
