First, find the total number of marbles that are both blue and striped. This would be the number in the intersection of the "Blue" row and the "Striped" column, which is 12.
Then, find the total number of marbles in the collection, which is given as 107.
The probability of randomly selecting a "Striped marble that is blue" is therefore 12/107, which cannot be simplified further.
So, P(Blue AND Striped) = 12/107.
