Let's consider the binary classification problem: Y $=\{+1,1\}$

Vector of correct answers:

$($y$1,...,$y$10)=(1,+1,1,1,+1,1,+1,1,1,+1).$

Vector of predicted values of some binary classifier:

$($a$1,...,$a$10)=(+1,+1,+1,+1,+1,1,1,1,+1,+1).$

Calculate: True Positive Rate $($TPR$).$

Note: round answer to hundredths
