Answer 1

Answer:

Step-by-step explanation:

Total number of students who roller skated = 80

Number of students who roller skated with laser tag = 39

Number of students who roller skated with no laser tag = 80 - 39 = 41

Therefore, percentage of students who roller skated with no laser tag = $\frac{41}{154}\times 100$ = 27%

Since, number of students who played laser tag = 85

Percentage of students who played laser tag = $\frac{85}{154}\times 100$ = 55%

Total number of students who played no laser tag = 45% of 154 = 69

Number of students with no roller skates and no laser tag = 69 - 41 = 28

Percentage of students with no roller skates and no laser tag = $\frac{28}{154}\times 100$        

                                                                                                       = 18%

Percentage of students who played with no rollers skates = (30 + 18)%

                                                                                                 = 48%

                                  Laser tag                 No laser tag                Total

Roller skate                     25%                           27%                      52%

No Roller skate               30%                           18%                      48%

Total                                55%                           45%                      100%
