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 = = 27%
Since, number of students who played laser tag = 85
Percentage of students who played laser tag = = 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 =
= 18%
Percentage of students who played with no rollers skates = (30 + 18)%
= 48%
Laser tag No laser tag Total
