Answer:

b 18

Step-by-step explanation:

From the given data: the right table arrangement is:  

 [tex]Actual \ Class[/tex]         [tex]\text{ Predicted Class 1}[/tex]                [tex]\text{Predicted Class 0}[/tex]

[tex]Class \ 1[/tex]                          18                                    11

[tex]Class \ 0[/tex]                           11                                   60

The True Positive is the number of current customers who were predicted to give references to a free back rub and who actually gave references to a free back rub.  

This number is given by the section in the segment relating to Predicted Class 1 and the line comparing to A[tex]Class \ 1[/tex]tual Class 1 which is 18.
