The major product of the following reaction is:

Electrophilic Addition:

Dilute sulfuric acid acts as a source of hydronium ions ($$\text{H}_3\text{O}^\oplus$$). The electron-rich carbon-carbon double bonds ($$\text{C=C}$$) undergo electrophilic addition by attacking the protons ($$\text{H}^\oplus$$).

Carbocation Stability (Markovnikov's Rule):

Protonation occurs selectively to form the more stable tertiary ($$3^\circ$$) carbocations rather than less stable secondary carbocations at both alkene sites.

Nucleophilic Attack by Water:

Water molecules ($$\text{H}_2\text{O}$$) present in the dilute medium act as nucleophiles, attacking both of the tertiary carbocations. After deprotonation, hydroxyl ($$-\text{OH}$$) groups are successfully attached to those positions.
