A is false because sum of 6 occurred 7 times and that's give us 7 / 50 = 0.14 = 14%, not 7%.
B is true because 10 or 11 occurred 9 times in total so that's 9 / 50 = 18%
C is false because 3 or 4 or 5 occurred 12 times in total so that's 12 / 50 = 24% not 22%
D is false because there are 20 dots in total for sum less than 7 so that would be 20 / 50 = 0.4 = 40%, not 60%
Final answer: B
Hope this helps.
