To determine the possible blood types of a baby when the mother has AB blood type (genotype IAIB) and the father has O blood type (genotype ii), we can analyze the potential combinations.

The mother can pass on either an A (IA) or a B (IB) allele, while the father can only pass on an O (i) allele.

Here are the possible combinations for the baby:

1. Mother (A) + Father (O) = Blood type A (genotype IAi)
2. Mother (B) + Father (O) = Blood type B (genotype IBi)

The possible blood types for the baby are:
- A
- B

Since neither parent contributes an O allele, the baby cannot inherit the O blood type.

Thus, the chance of the baby inheriting the O blood type is **0%.**
