Using the Punnett square, 1/4 children will have the disorder.
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
A. 1/4 * 1/4 = 1/16
B. (1-1/4)^3 = (1-1/4)(1-1/4)(1-1/4) = ?
Use similar method for the other problems.
