Answer:

A

Step-by-step explanation:

B doesn't work because you can have people who are in a band and not in a band at the same time, which is showing in the first spot

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Number of students asked in a survey = 60

Number of students who play an instrument = 35

Number of students who are in band = 30

Number of students who are not in band = 30

So, the two way frequency table would be :

                                          Play instrument     Not play instrument    Total

In band                                       30                             0                           30

Not in band                                  5                             25                          30

Total                                          35                             25                           60

Hence, option 'a' is correct.
