No one can tell what percentage of their children will have blood group O or B.
What we can tell confidently is that each child they bring into the world has a 75% probablity chance of being blood group B and a 25%chance of being blood group O.
It's possible they have 10 children, and all have blood group O despite the lower 25% probability of having blood group O in each child. That means each of the children favoured their 25% chance.
