Percentage range


#1

In the FAQ, it mentioned that for a 10% event
'If you run your “experiment” 1000 times, the number of times the event happens should be in the range (50, 150)."
does the 50 and 150 include in this range?


#2

Yes, 50 <= x <= 150 is the range mentioned (though in practice, it doesn’t really matter)
