I am trying to calculate the Laplace probability estimate according to this formula: enter image description here The correct answer is $0.733$ but I just don't know how to find the number of examples that belong to the Class and the number of all examples in the given set. I tried multiplying 4*12 as the number of all examples in the set, but doesn't seem to quite work.
