Answer:
34% of nineteen year old males are less than 146 pounds
Step-by-step explanation:
The complement of a set A is the set of all the elements in the universal set but are not in the set A.
Let A = 66% of nineteen year old males are at least 146 pounds
The universal set, U = 100% of nineteen year old males
Note that 100% - 66% = 34%
Therefore, the complement of the given event is:
A' = 34% of nineteen year old males are less than 146 pounds
