Below is the confusion matrix when classifying $1,000$ mortgages $($in a validation set$)$ that a bank extended to applicants, into either a default $(1)$ or a repayment $(0)$ status using a classification tree. Unfortunately the contents in most of the cells are unavailable.

$1.$ What is the correct classification rate? Please express your answer as a percentage, answer to the $10$th decimal place.

$2.$ If you are told that a particular mortgage from the validation set has been repaid, what is the probability that your model misclassified it as a default? Provide a numeric estimate. Please provide your answer by rounding to nearest thousandth decimal place and do not put a $\%$ sign at the end of your answer.

$3.$ Populate the missing values of the table.
