The probability that they will have exactly one affected child is 9/64.
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
The likelihood that a population parameter will be less than a given value when the null hypothesis is true is expressed as the p-value, also known as a probability value or a measure of significance, for a particular statistical model.
Probability of affecting for 1 child = 3/4 = q
Probability of not affecting on 1 child =p=1/4
Formula:
P( exactly one affected child )
= [tex]^{3}C_{1}[/tex] * * (1/4)² * (3/4) = 9/64
