Addition of HX to Alkenes
Using the drawing pallet on the right, draw the structure of the major organic product for the reaction shown below:

   

The addition of HCl to an alkene proceeds through a carbocation intermediate and results in the formation of an alkyl chloride with the chlorine bonded to the alkene carbon which would form the most stable carbocation (Markovnikov addition). Rearrangements are commonly observed. In this reaction, the tertiary carbocation is preferentially formed.

The addition of HBr to an alkene proceeds through a carbocation intermediate and results in the formation of an alkyl bromide with the bromine bonded to the alkene carbon which would form the most stable carbocation (Markovnikov addition). Rearrangements are commonly observed. In this reaction, the tertiary carbocation is preferentially formed.

The addition of HBr to an alkene proceeds through a carbocation intermediate and results in the formation of an alkyl bromide with the bromine bonded to the alkene carbon which would form the most stable carbocation (Markovnikov addition). Rearrangements are commonly observed. In this reaction, the initially formed secondary carbocation undergoes a 1,2-methyl shift to give the tertiary carbocation, which adds the bromide anion.

The addition of HCl to an alkene proceeds through a carbocation intermediate and results in the formation of an alkyl chloride with the chlorine bonded to the alkene carbon which would form the most stable carbocation (Markovnikov addition). Rearrangements are commonly observed. In this reaction, the tertiary carbocation could be formed on either carbon.

The addition of HBr to an alkene proceeds through a carbocation intermediate and results in the formation of an alkyl bromide with the bromine bonded to the alkene carbon which would form the most stable carbocation (Markovnikov addition). Rearrangements are commonly observed. In this reaction, the secondary carbocation does not rearrange since a tertiary bridgehead carbocation would be formed.

That is correct!
Sorry, that is not correct. You should modify your structures and try again. Remember that the initially formed carbocation may rearrange to form a more stable carbocation center and that halogen anion will add to the most stable carbocation.
You have to enable Java and JavaScritpt on your machine !
