Expert Solution

Step 1
To find the probability that person is from US, if we know that the person has 1 child:
Conditional probability is the probability of event A when event B is known and it is given by the formula:
Let A be an event that the person is from US and B be an event that the person has 1 child.
From the table, number of individuals who have 1 child is 22
Intersection of an individual having 1 child and the individual is from the US is 20.
