Question 37: An, Tu and Binh write together the set of natural numbers greater than 5 and less than 8. An writes: \(M = \left\{ {7;6} \right\}\), Tu writes: \(T = \left\{ {6;7} \right\}\), Binh wrote: \(B = \left( {6;7} \right)\). Out of the three of you, who wrote it correctly?

The set of natural numbers greater than 5 and less than 8 is \(M = \left\{ {7;6} \right\}\), \(T = \left\{ {6;7} \right\ }\)

An and Tu wrote correctly, Binh wrote wrong.
