Solution

30 cases were classified as normal by both the physicians as given in the table

40 cases were classified as abnormal by both the physicians as given in the table

Percentage agreement = (30 + 40)/total number of cases

=> 70/100 = 70%

Since the normal cases should be excluded from the calculation

Hence the answer to the problem will be

=> 40/100 = 40%
