Which of the following intervals is the largest?
{1,3}
(1,3)
[1,3)
[1,3]
As we have learnt
Intervals as Subsets of R -
There are two brackets used:
[ ] is closed where elements are included in the beginning and end.
() is open where elements are excluded in the beginning and end.
[) is Closed-open where elements in the beginning is included and in the end is excluded.
(] is open-closed where elements in the beginning is excluded and in the end is included.
-
in [1,3], both 1 and 3 are included. So it is the longest interval.
