Step-by-step explanation:

Given that a woman with blood type O is expecting a child. Her husband is blood type A. Both the woman's father and her husband's father had blood type B.

To find out the probability that the child will have type O blood

We have that a child blood group does not depend on parents or grand parents.

Each child is borne independent to have any one of 4 blood groups with equal chance

Hence prob that the child have type O = 1/4 = 0.25
