In the list 3, 4, 5, 5, 5, 5, 7, 11, 21, what fraction of the data is less than the mode?  Choose the correct choice.
A) 2 / 9  B) 1 / 3  C) 2 / 5  D) 2 / 3  E) 7 / 9

Rationale: highest frequent term in the set is 5 ( with frequency 4 ) hence mode = 5 two terms ( 3 , 4 ) out of a total of 9 terms are less than mode of the set . fraction of set that are less than mode of set = 2 / 9 answer : option a
Answer: A
