Answer 2

Answer:

(a) Students not liking any sports= 7

(b) Students liking exactly one sports= 21

Step-by-step explanation:

Mrs. Grady surveyed 30 students.

11 of which said they liked basketball, 14 of which said they liked hockey, and 2 of which said they liked both sports.

Total students liking sports= 9+2+12

                                             = 23

(a) Students not liking any sports= 30-23

                                                  = 7

(b) Students liking exactly one sports= 9+12

                                                        = 21
