In the list 1, 2, 3, 4, 5, 5, 5, 5, 7, 11, 21, what fraction of the data is less than the mode?  Choose the correct option
A) 2/9  B) 1/3  C) 2/5  D) 4/11  E) 7/9
Mode: The mode of any set is the term which has the highest frequency (Occurrence)   Highest frequent term in the set is 5 (with frequency 4) hence   Mode = 5   four terms (1, 2, 3, 4) out of a total of 11 terms are less than mode of the set.   Fraction of set that are less than Mode of set = 4/11   Answer: Option 4/11
