Precision is a metric used to evaluate the performance of a classification model. It measures the proportion of true positive predictions out of all the positive predictions made by the model. In other words, precision tells us how many of the predicted positive cases are actually correct. A high precision indicates that the model does not frequently misclassify negative cases as positive.
There is a circular park of diameter 65 m as shown in the following figure, where AB is a diameter. An entry gate is to be constructed at a point P on the boundary of the park such that distance of P from A is 35 m more than the distance of P from B. Find distance of point P from A and B respectively.
