I think that in acid, double bonds get hydrated.
So your products are
HO-CH2-CH(CH3)-CH3 and (CH3)3 -COH

The former is less sterically hindered, so I think it would be the more abundant product.

The olefin is hydrated in a two step process. First step is the attachment of a hydrogen ion to one side of the C=C and two carbocations are  possible (CH3)3C+ and (CH3)2CHCH2+. The first is much more stable and so the major product is (CH3)3COH.
