7. Given the cost matrix below: Actually Belonging to Class Actually Belonging to Class 0 Classifying as Class C 00 0 Classifying as Class C 10 C 11 and the probability of a test instance belonging to class 1 is p, find the threshold t such that it is optimal (i.e., minimizing cost) to classify the instance as 1 if p > t and it is optimal (i.e., minimizing cost) to classify the instance as 0 if p
