Dado el intervalo B=(-5;-2), marcar las afirmaciones correctas

El conjunto B es: B={xϵR : x>5 x<2}B=\left\{x\epsilon R\ :\ x>-5\ \vee\ x<-2\right\}

El conjunto B es: B={xϵR : 5<x<2}B=\left\{x\epsilon R\ :\ -5<x<-2\right\}

El conjunto B es: B={xϵR : x>5 x<2}B=\left\{x\epsilon R\ :\ x>-5\ \wedge\ x<-2\right\}

El número -5 pertenece al conjunto B

El número 0 pertenece al conjunto B
