In the list 3, 3, 4, 5, 5, 5, 5, 7, 11, 21, what fraction of the data is less than the mode?  Choose the correct choice from the following:
A) 2/9	B) 3/10	C) 2/5	D) 2/3	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   three terms (3, 3, 4) out of a total of 10 terms are less than mode of the set.   Fraction of set that are less than Mode of set = 3/10   Answer: Option 3/10
<result>B</result>
