Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
first of all i also thought the answer should be D but i chose B finally... the question said the first number is 3 statement 1 says that the range= highest-lowest there would be 2 cases: every number in the set is 3 3 3 or the highest number is 3 and the second and the third are both 0 becuase the question doesnt say that the numbers in the set must be in order, we cant conclude anything about this statement.
