So, you have a type A, which means one has A, you have a B, which means one has B
So right now, Parent A has a blood type of A, and Parent B has a blood type of B
Now a child has AB, which is a possibility figuring that A and B are options
Now that a child has O, which is only a possibility if both parents have O, the Genotype of your parents are AO and BO.
Hope this helped :)

Genotype of the mother with freckle trait is rr. This means that it is a recessive trait.
Genotype of of the father having clear facial skin is Rr, showing that it is a dominant trait. There can be two genotypes for this trait that is Rr and RR.
When these parents are crossed, they produce 50% offsprings with the freckles trait (rr) and 50% with clear facial skin ( Rr).
Therefore, the likelihood of the first child with freckles is A
