Answer 9

no, say the father has A blood and the mother has B, the kid might have O if both of their parents have AO and BO as the genotype because he/she inherits one allele (A, B, or O) from each parent

EDIT: no the child of parents with A+ and O+ can not be AB+, because the genotype of A+ blood is either AA or AO and the genotype of O+ is OO, so the child will inherit one allele from each parent. the child would therefore either have type A (50%) or type O (50%).
