The major product (the product made in the largest amount) is the one where the H atom was added to the C=C carbon atom that had the most H atoms attached to it at the beginning. The minor product (the one produced in the smaller amount) is the other one where the H atom was added to the C=C carbon atom which had the least H atoms attached to it at the beginning.

The major product forms when the H is removed from the neighbouring carbon that has the fewest H atoms. If the alcohol/haloalkane is asymmetric, both neighbouring carbons have the same number of H atoms, both products form in equal amounts. Therefore, there is no major or minor product.
