Statement 1: Addition of HBr to ethene proceeds via carbocation intermediate 
Statement-2: Addition of $B{r}_2$ to alkenes is an example of electrophilic addition,

Addition of  $B{r}_2$ on trans-2-butene gives meso-2, 3-dibromobutane. It follows anti-addition. Hint: T A M – Trans alkene (sym) on Anti addition gives meso product.$B{r}^{+}$ is the electrophile attacking in RDS.
