Задание

Пусть \(\displaystyle A=[1;7] \small,\)\(\displaystyle B=[3;9] \small.\)

Найдите \(\displaystyle A\setminus B \small.\)

\(\displaystyle A\setminus B =[1;3)\)
\(\displaystyle A\setminus B =(1;3]\)
\(\displaystyle A\setminus B =\varnothing\)
\(\displaystyle A\setminus B =[1;3]\)
\(\displaystyle A\setminus B =(1;3)\)
