Hm, that's interesting. So you say that 1 ≥ x ≥ 10 is equivalent 1 ≤ x ≤ 10? Or I do understand it wrong somehow?
it is simply compressed what you write is 35>=Ballpicked>=72
but what you must think is:
35>=Ballpicked and Ballpicked>=72
so it says
35 is greater then or equel to ballpicked
and BallPicked is greater then or equal to 72
But I think something went wrong in the writings
since 35 has to be bigger or equal to ballpicked while at the same time ballpicked has to be bigger or equal then 72
so 35 should be bigger then 72
so there is something wrong here
